I pointed this out on IRC, but just to make sure it hits the list...
Turning of PREEMPT will change the module ABI. ia64 also has PREEMPT
turned on in 2.6.8 (following suit w/ x86), and I've left it on for this
reason.
If this is considered worth another ABI change, then I'll disable
PREEMPT on ia64 as well.
