OT: Brooktree IC used in cg3 graphics framebuffer?

[Mark Cave-Ayland]

Hi all,

A slightly off-topic question, however there may be some people on the 
list who will know the answer to this: what was the number of the 
Brooktree IC used on the cg3 framebuffer? According to various sources, 
it looks like the BT458 was used on the cg6 - is this the same as the cg3?

ATB,

Mark.
