Hi,
i'm taking suspend-devel into cc:, so you'll probably get a faster
turnaround time for the next mails :-)

You probably need to start debugging on the kernel level. Using firescope
or the beeping patch could be a start.
SysRQ still working means it comes back somewhat, but probably does not
make it into userspace.
If your kernel is not pretty new (around 2.6.18 or newer), booting with
"noapic" is also always a good idea for troubleshooting.
Good luck :-)
