funnily, i found out that indeed booting the machine with the display
connected via DVI does *not* result in a functional setup. when you
boot with the display turned on and connected via the VGA connector, X
runs fine. being at text mode (console) i switched the cables, i.e.
disconnected the VGA cable and connected the DVI cable to the card
(which is only capable of DVI-A, obviously). starting X (xfce in my
setup) works (still).

so after all i need another card, ideally capable of DVI-D output. best
would be a card which features two DVI-D for dual head setups (some
day), maybe they are still expensive, but the question itself is for
free :)

so, can anybody recommend a card with DVI-D output, passively cooled,
and with good support from XFree/

(i'm not willing to fiddle around with binary [linux] drivers by ATI,
nVidia et al. as i run NetBSD as well on macppc and i'd like to
consolidate drivers etc.)

thanks (in advance!),
