Please, still try to get the HV folks to add more VESA modes for use by
linux :-) 1600x1200 would be nice for example, as would 1440x900 (lots
of cheap flat panels do that nowadays.... they can demote to 720p which
is good enough for games, but for linux, we want native resolution).

So the whole thing should be turned into a state machine on a timer or a
kthread no ? So at least, whatever issues the mode change can start
drawing while the kernel waits to actually enable the outputs...
Ben.
