Hi Mikael, I think you are the "guy" whose propose this patch on lkml.
I am forwarding to ACPI ml, where is the right place to send ACPI
patches.

"2.4.27-rc1 reintroduced the double-speed timer ACPI bug. 
Both x86-64 and i386 are affected.

The patch below fixes it on my box. It's a backport of a
patch Hans-Frieder Vogt made for 2.6.7-bk2, extended to
also handle i386.
