Comment 2 for bug 201946

Ok. I was finally able to resolve this problem to some extent.

Cleaned up dmesg greatly by adding "lapic" to the kernel line in kernels 2.6.22-14 and 2.6.24-12.

Also changed a config setting for cpu to "custom" in the system bios.

Finally ran "sudo dpkg-reconfigure xserver-xorg.

An xorg.conf file was written to /etc/x11 where previously there had been none...only something in /usr/share/xresprobe....I believe.

Anyway dmeg looks much better. Synaptics touchpad is finally scrolling and 2.6.22-14-generic seems good.
Still no sound in kernel 2.6.24-12.
