I tried that, but like I said fdisk complained when the svnd device is

associated with the raw direct access disk device. For example
# vnconfig -k svnd0 /dev/rwd1c
# fdisk -c 19457 -h 255 -s 63 -i svnd0  # disk CHS

fdisk: error initializing MBR: bad address
# fdisk -c 19456 -h 254 -s 63 -i svnd0  # OpenBSD partition CHS

fdisk: error initializing MBR: bad address
# fdisk -i svnd0

Warning CHS values out of bounds only saving LBA values
