I had a similar issue with an old computer. I don't know why, but ACPI 
whas messing with the computer internal clock. I just turned if off 
(removed from the kernel, but there should be an option to disable it) 
and the problem disapeared.

The linux kernel have a blacklist for ACPI. If the machine is older than 
some years (it's set in the kernel configuration) it disables ACPI. 
Maybe the kernel change between SL10.1 and FC5 changed this date.
