Binary package hint: xorg

I've recently upgraded from my perfectly working 8.10 to 9.04 beta. I'm using the amd64 version. Everything in the system is up to date as 31/04. I've also used memtest86+ and everything is ok.

Since I upgraded, the system randomly freezes, allowing me to move the mouse, but stoping to respond to anything else (it happens at very random time intervals, sometimes very close to each other, sometimes not so). Sometimes, the caps lock light flashes, but not always. Can't change to a text terminal using alt+ctrl+f1-6. Using alt+ctrl+bckspc doesn't work either (I've disabled don't zap flag, so it works when the system is responding). I have to power down the system holding the power button down (its a laptop, so I don't have a resert button).

The system is a HP Pavillion dv2735la. I think there's more details of the hardware in the files I'm attaching (its the first time I report a bug, novice ubuntu user, around 4 month using it).

If you need any information just ask, as I don't know much about debbuging errors please explain where to find it.

PD: also having trouble at normal shutdown, after usplash I'm left with a blinking cursor, if I press alt+ctrl+del it says "md: stopping all md devices" and then reboots. This also didn't happen with 8.10. Could this errors be related? Or should I file another bug?
PDD: didn't try REISUB trick, as I didn't know it, will try next time.
PDDD: sorry about my english, i'm from Argentina.
