The problem is due to this patch:

 http://linux.bkbits.net:8080/linux-2.5/diffs/drivers/acpi/acpi_osl.c@1.3?nav=index.html|src/|src/drivers|src/drivers/acpi|hist/drivers/acpi/acpi_osl.c

Changing #if 0 to #if 1 gives me a working kernel (2.5.17).

I haven't had time to look into a proper fix (need to finish the new
TLB flushing code first).
