Fix VT switching on M6 chips
Some M6 chips have a faulty MEM_SIZE register that in
some cases reports 0 on 8 MB cards. On EnterVT we check
the MEM_SIZE reg as a check to see if the card is posted or
not. Since this reg returns 0, the driver attempts to post
the card which can lead to a hang. Switch this to check if
either crtc is active as is done in the bios init code.
