Welcome!  I also wanted to do this for very long time but I had no
time and test machines ;)
Recently I got Core Duo (Thinkpad X60) and Core 2 Duo (X61) machines.
I have some more ideas on wakecode but I'm not sure whether it is possible

Hmm, my knowledge on recent hardware is very poor, so your comments
are very helpful to catch up.  Thanks.

Yeah, I thought that we need INT10 to set video mode again in
realmode, but found it can be done in protected mode with
x86bios_intr(), great!

Anyway, thanks for many things!
