Does anyone have access to the VESA VGA BIOS extension spec >=V1.01 ?
(or can point me to where I can get it, via ftp preferably).

I'd like to know how function 4F06 (Get/Set logical scan line length)
and function 4F07 (Get/Set Display Start) are supposed to work in  
text mode.  Are all parameters specified & returned in chars rather
than pixels?  If so, this would mean function 4F07 would only allow
panning in char blocks.
