I found video kernel option explanation on

I add

video=DVI-I-1:1280x1024-24 at 60e video=DIN-1:1024x768-24 at 60e

into grub/menu.lst but it affects only DVI-I-1 output, it looks like 2nd 
video option is ignored.

Also I try to add single "video=DIN-1:1024x768-24 at 60e" without success.

In dmesg I can see "forcing DVI-I-...." but can not see anything about DIN
