Save yourself some grief:
1) get a $5 USB stick from $discount_store
2) install a OpenBSD on a bootable partition on the stick
3) boot the laptop into OpenBSD from the USB stick
4) examine the dmesg output, and save a copy
If you don't have physical access to the laptop (eg. buying online) then
you're SOL and can only hope for the best. I'm sure others here will
point out that the "SuperCard 2000" might have the same packaging
outside, but different chipsets inside.
Booting it and looking at a dmesg is the only way to know 100%.
