I can confirm that pwaller's workaround works.

Steps I took:
Install Kubuntu
Reboot, when I get to the grub screen edit, the kernel command line and add acpi=off to the line
Boot
Kubuntu starts up but freezes every 30 s or so.
Follow the guide at http://www.ubuntuforums.org/showthread.php?t=157560 for installing a new kernel. In my case, 2.6.17.7. Note that on my z96j, I got a lot of warnings showing up in my syslog about asus-acpi not being able to determine the LCD settings. In the end, I modified /usr/src/linux/drivers/acpi.c, function static int get_lcd_state(void) so that the body of the function is simply: return 0; (all other lines removed). This stops the warnings from cluttering up syslog.
Reboot
(no need to specify acpi=off)
Now, you'll find that the ipw3945 driver is now broken. Download the latest from ipw3945.sourceforge.net and follow the instructions on installing it.

And that's it! I haven't played around with the ATI binary driver yet but it'll probably be the same as the ipw3945 driver (i.e. have to install manually).

But it is good to know that whatever bug there was is fixed in later kernels.
