Uh.... That might work.... Except that after applying the patch & 
restarting. Then suspend-resume I get another small problem... My 
thinkpad (r50p) uses the power button to wake up from suspend... The 
system wakes, but with this latest patch, acpid then kicks in & says 
'Ohh! I saw him press the power button' and promptly shuts down...

here's my acpid logfile

Sleeps, wakes & a shutdown... Should acpid do that? (i.e. shouldn't it 
eat the power button event that woke it up as a wakeup? Should it even 
get that?) Or is it the previous patch for drivers/acpi/sleep/main.c 
resetting the IRQ9 to edge triggered that's killing me? (I'll try 
removing that now).

TIA
Hamish.
