new kernel problems

[Efthym]

hi all,

I installed the new kernel today 2.6.12-1.1447_FC4 on my T21.
1. ibm-acpi module was not autoloaded. These are on the only meesages in  
dmesg:

Using generic hotkey driver
toshiba_acpi: Using generic hotkey driver

2. acpi keeps giving an error about its owner (??)

00Aug 29 19:18:35 purgatory kernel:     ACPI-0145: *** Error: Invalid  
owner_id:


can i fix this or ... go back to the old kernel ?

Thanks for any hints

Efthym

P.S is there any chance in the near future for ibm-acpi being upgraded to  
v0.11 in the default kernel ?
