It's not that big of a deal for userspace, you just need scripts to 
unload any problem device drives before suspend and reload them after 
resume. You would also need to kill and restart any programs that will 
be broken by those devices going away. APM already has config files that 
specify a lot of this which could probably be adapted to ACPI. But the 
ultimate goal is to get devices that don't even need to be unloaded, 
since we now have proper suspend/resume hooks. ;)

I think there is a "pmsuspend" program floating around out there, don't 
know how well it has been integrated with existing suspend/resume 
scripts though. Otherwise you can just talk to the kernel directly...

Oh, and there's that annoying little problem where acpid sees the button 
press that I have to use to resume, as a shutdown event...
