I don't know whether that is possible.

Patch attached. Before you suspend, please run
# dmesg|grep -C5 radeon
and save it somewhere. There should be a line
"radeonfb: Acer test detected, enabling workaround"
If so, try suspending and resuming. It should Just Work(tm).
Warning: It may look like your screen "melts" for up to two seconds while
suspending. This is nothing to worry about and usually only happens on the
second and subsequent suspend cycles.
Suspend and resume should be fast, it takes my machine about 2 seconds to
perform each of them. If your machine needs more time (especially while melting
the screen), something is wrong.
Oh, and please suspend with
# echo mem >/sys/power/state
at least while you're testing.

Carl-Daniel
