Oak is Oak, neither Tseng nor PVGA. There are actually two chips. The Oak-37
and the Oak-67. The former will do 256 colors only at 320x200, the latter will
go to 800x600 with 512kb RAM. It has separate read/write pointer bank switching
registers, so it could work with Tom's server. The address/bits of those 
registers are incompatible with Tseng though.
