Installing Ubuntu Jaunty on HP DV2 laptop

I recently purchased an HP dv2-1028 with AMD neo cpu, and an ATI 1250x, without a CD player. This was surprisingly a painless install, but there were few issues that arose, which I'm posting here (along with few solutions).

First off, since this laptop does not have a cd-player, I needed to setup a usb boot disk. Quick search brought me up to http://www.pendrivelinux.com. I followed the instruction for installing 9.04, but for some odd reason that failed (the USB key claims that it can't find the mounted partition. Seems to be the duplicate of https://bugs.launchpad.net/ubuntu/+bug/366678), so I installed 8.10 instead which went ahead with a hitch. In fact, I was impressed on how quickly it could install the whole thing.

After the installation, the laptop was fully functional: sound, suspend/hibernation, nice video, they were all working fine. The only issue showed up when I was trying to test the webcam. Apparently the ati driver for 8.10 doesn't support xvideo extension, and as result, cheese would crash upon start. Installing fglrx solved that problem, however that broke the hibernation/suspend issue (hmm... I'm pretty sure my laptop was not functional after wakeup, but it's possible that it was just the display. If someone has any experience in that regards, they can correct me). I didn't stay in 8.10 for that long, but it seemed like a solid system (minus the issues mentioned, which I'm sure one can fix if they spend a bit of time on it).

After noticing the problem with hibernation/suspend issues, I upgraded to 9.04. To my surprise, my laptop would crash upon startup with garbeled display. Searching the web a litte, I find out that fglrx and 9.04 are not quite compatible (I can't find the wiki page that says that, but it was from ubuntu's website), and it was strongly suggested to remove fglrx before upgrading. So, I remove fglrx, and switch back to the open source driver, and reboot, and it works like a charm. xvideo extension is working now, so cheese is functional. In fact almost everything is working without a hitch: webcam, video card, video replay, wireless, suspend/hibernation (although, see below). The only issue was the lack of sound from the internal speakers. This is apparently a known problem, and following the suggestion at
http://ubuntuforums.org/showthread.php?t=1073090
solved the speaker issue.

The only issue left, is not everything starts up automatically after a suspend/wakeup cycle. Specifically, the monitor is initially off, and I have to switch to text and back to graphic mode to make it work again (minor annoyance), and the wireless needs to be enabled manually afterward. I'm not sure if anyone has any suggestion how to fix these issues, or if it is unique to my setup. However, aside from these, the laptop seems functional, and I am a very proud user. I am in the euphoric state that makes me pity the people using other OS'es right now.

Thanks Ubuntu,

UPDATE: I spoked too soon. In the default setting, after waking up from suspend, vbetools is using ~90% cpu, as well as the issues mentioned above, and I could not suspend again. The workaround in https://bugs.launchpad.net/ubuntu/+s...ol/+bug/130979 solved the problem. Specifically adding

      <match key="system.hardware.product" contains="HP Pavilion dv2">
        <merge key="power_management.quirk.none" type="bool">true</merge>
      </match>

just under the prefix="Hewlett-Packard" fixed the problem.
