[Soekris] Best way to install openbsd

[wkeen@blowthebridge.net]

can anyone reccomend a good way to install openbsd without too much work? 
I've got a 4801 and need openbsd with some utils (bind, openvpn, etc) to
be installed, and i'd like all the normal things to be installed too like
man pages, but worry about getting a ramdisk running as this 'll be my
first time playing with ramdisks on openbsd.

Any words of advice from anyone? - or a cf card image perhaps? - the cards
i have are 512mb
