ah, thanks, sorry i missed that.

have you tried printing the oem_string from the vbe control info
structure? i'm getting jibberish when i try but the only thing i can
think of doing is what they did in get_str() (page 78) in the vbe spec
by changing the far ptr to a near one. but i thought i wouldn't have
to do that because i'm in the same segment?
