And so far no one has tried to comment on those 2 dmesg lines I've quoted a couple of times now, here's another:
[ 0.000000] Nvidia board detected. Ignoring ACPI timer override.
[ 0.000000] If you got timer trouble try acpi_use_timer_override
what the heck is that trying to tell me to do, in some sort of broken english?
..

I think it says this:

"If your system is misbehaving, then try adding the acpi_use_timer_override
keyword to your kernel command line (/boot/grub/menu.lst) and see if it helps."

So, you can either hardcode it in /boot/grub/menu.lst (just add it to the end
of the first line you see there that begins with the word "kernel".

Or you can just try it temporarily at boot time (safer, but tricker),
by catching GRUB (the bootloader) before it actually loads Linux.

Usually there's some key or something it says you have 3 seconds to hit for a "menu",
so do that, and then use the cursor keys to find the first "kernel" line in that menu
and hit "e" (edit) to go and add the acpi_use_timer_override keyword to the end of
that line (same as above).
..

Minor correction (having just tried it here): once you see the GRUB (boot) menu,
hit the letter e to edit the first entry, then scroll to the "kernel" line,
and hit the letter e again to edit that line. It should put you at the end of the
line, where you can just type a space and then acpi_use_timer_override and then
hit enter to finish the (temporary) edit. Then hit b for boot.
