software suspend and modular IDE in 2.6.4

[Arkadiusz Miskiewicz]

Hi,

I'm using kernel with modular IDE (modules are loaded from initrd). suspending 
to disk works fine (it seems) but resume won't since kernel is trying to 
resume before running initrd so I'm getting resume failed
Resume Machine: resuming from /dev/hda2
Resuming from device unknown-block(0,0)
Resume Machine: Error -6 resuming
and then initrd loading proper modules + machine starts as normal boot (see 
log below).

Would be it possible to delay resuming after loading initrd? Or some userspace 
utility that would run from initrd after loading IDE modules and forced 
resume from swap?
