If this is a VM, create a new (larger) virtual disk, attach to the VM, and create a proper MBR partition table, then use dd to copy the old disk contents into the OpenBSD area on the new disk, leaving the MBR intact.
I would do the last part from ramdisk kernel. You may need to re-install the boot loader onto the new disk. If you do everything carefully, this method should be non-destructive. I'm shocked this has worked at all, given the MBR contains the boot code.
