No, it is not possible.

Just tell the BIOS it's 33.8 and then change the geometry to 'disk' ('g d'
while in disklabel -E) when you run disklabel. OpenBSD doesn't use the BIOS
for anything other than loading the bootblocks and kernel, so it's not a real
big deal: just make sure the / partition is within the BIOS addressable area.
It will probably work fine.
The PC BIOS will always be limited in some way or another, we used to do the
same thing before LBA was common.
