Not quite, but close...

With just dsub and no params, we get a perfect 1600x1200 (200x75) console

With DVI and video=nvidiafb:1600x1200-32@60 I get a kernel hang like this 
(copied by hand and shortened in places)

Decompressing linux
Bootdata ok (command line is root=... video=nvidiafb:1600x1200-32@60)
Linux version 2.6.10-rc2 ...
BIOS-provided physical map
Scanning NUMA topology in Northbridge 24
Number of nodes 2 (10010)
Node 0 using interleaving mode 1/0
No NUMA configuration found


and thats as far as it gets.

Getting closer by the hour :)
