ubuntu kernel boot very slow on acpi/ahci probe

I see a 45 second delay between an ACPI interrupt assignment and the first
line of the AHCI driver where it reporets the slots, ports etc.
the machine is a thinkpad T60P with ICH7 chipset. the system is latest
(k)ubuntu dapper with latest i686 kernel (smp, cpu is core duo).

Any idea how I can speed up the boot process?

Thanks for your help.

Regards, Andreas
