OpenBSD 4.3 is due out on May 1st, a lot of changes have happened in 5 months.. perhaps you should wait for the 4.3 release, or try a snapshot from your local mirror, unfortunately, those are -CURRENT.. which, will eventually be the 4.4-RELEASE.
Reporting hardware incompatibilities for a code base several months old isn't very productive... 4.2 was released in November. ;) -Nix Fan.
