Experienced something similar today with a Gigabyte board from the Core 2 Duo
era. (this may not be an OpenBSD problem in my opinion)
Used an disk with a working Fedora 20/OpenBSD 5.4 install on it to do a clean
install of OpenSUSE 13.1. Upon first boot the system hangs in the Intel AHCI
screen. Normally a list of SATA ports and connected disks would appear but
nothing happens.
Eventually the simple solution for me was to use the second SATA controller
this board has. So it may be an issue with how the Intel SATA BIOS detects
the disks.
I don't want to waste more time on this so I'm posting some minimal info which
may or may not useful:
The disk originally had its first partitions start at offset 63:
Disk: sd0 geometry: 9729/255/63 [156301488 Sectors]
Offset: 0 Signature: 0xAA55
Starting Ending LBA Info:
#: id C H S - C H S [ start: size ]
-------------------------------------------------------------------------------
*0: 83 5660 19 56 - 5723 208 53 [ 90929152: 1024000 ] Linux

3: A6 0 1 1 - 5659 254 63 [ 63: 90927837 ] OpenBSD
Now, in the non-working situation, it starts at 2048 (first MB was reserved by
the OpenSUSE installer).
Another disk that used to work has its first partition start at offset 64:
Disk: sd0 geometry: 7297/255/63 [117231408 Sectors]
Offset: 0 Signature: 0xAA55
