Fwd: [9fans] VBE 1.2/2.0+ functions for Plan9

[Bob Hartley <bob.hartley@rogers.com>]

Please correct me if I am wrong on this:
Is it true that the XFree86 device driver modules are platform 
portable, as long as they are for the same instruction set 
architecture?  For some rason I thought the Linux and BSD mobs could 
swap video drivers around amoungst themselves.

If so, would it be possible to create some sort of adapter code that 
would wrap the x11 device drivers for Plan9 use?

Sorry if this is a naive/misbegotten thought,

regards,

Robert
