OpenBSD on the desktop / 3D acceleration / printer

[Christopher Intemann]

Hi,
I'm thinking about installing OpenBSD on my desktop workstation.
As far as I know, there are commercial (binary) drivers for some Nvidia and
ATI cards applicable.
Do these drivers work on OpenBSD as well?
If not, which graphics cards are supported for 3D acceleration at all?
Then, I would like to connect my USB printer/scanner (Epson SX100).
>From what I've learned from google, this device should work with Linux - but
does it work with OpenBSD?
Thx,
 Chris
