vesa(4) has video BIOS init hack run in vm86-mode or on x86 emulator.
I think it is cool.  My X61 still need video BIOS init in
acpi_wakecode, because it seems vesa's BIOS init ends incompletely by
page fault for now though.

If you have a vty with initial video mode, switching vtys will work I think.

Oh yes, please try the following patches.

This is already done in vesa(4), added support non-vesa mode.

Long time ago, I added the hack trying to make it as small as possible
for the same effect :)
Now we need the true solution...

Thanks!
