It can be done in the PROM, using the NVRAMrc stuff.

cg14config(1M) in Solaris 2.5.1 is a pretty nice interface to doing this.

Here's a snippet of the EEPROM setup on a SPARCstation 20 that had a GX
added to it, and which was set up to be 1280x1024 before it was (very recently)
upgraded (?) from 4.1.4 to 5.5.1:

[...]
silent-mode?=false
use-nvramrc?=true
nvramrc=probe-sbus
: vsetup " 135000000,81128,76,32,64,288,1280,2,8,32,1024,COLOR,0OFFSET" ;
vsetup 4
" /sbus/cgsix@1" " override" execute-device-method drop
install-console
banner

sunmon-compat?=false
[...]

These EEPROM nvramrc settings are all documented someplace in hardcopy, but
damned if I can remember where at the moment ...
