There's no generic method to initialize an SVGA to anything larger than 720x400 (or 720x480) for text displays. The major handicap is that wider displays need a higher clock frequency, and in particular for modern boards with their clock synthesizers, this becomes very tricky and hardware-dependent. Remember, the amount of hardware-specific code in XFree86 is about 200000 lines! -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
