ACPI problems in 2.5.68

I get the following errors when booting 2.5.68:

evevent-0286: ***Error: No installed handler for fixed event [00000000]
evevent-0286: ***Error: No installed handler for fixed event [00000003]
evgpe-0396: Error: acpi_ev_gpe_dispatch: No handler or method for GPE[ 0], disabling event
evgpe-0396: Error:
And the kernel locks up hard. Have to hit the reset switch. These
messages come just after mounting / readonly (thus, no logs exist;
had to copy these down by hand).

This is on a Toshiba Satellite 1605CDS. I'll try to provide whatever info
I can, if you tell me what to look for (and I can find it; a lot goes by very fast)
