vbetool is a program that IIRC drops into real mode, and allows INT10 
calls to be made.  One INT10 call allows you to 'boot the video card'.

From the driver perspective it is very brute force and may not work in 
all cases, but is a suitable work-around until we (ATI) have our ACPI 
support complete (can't discuss a schedule thought).
