Anecdotal but as far as acceptance (only dorm housing at my school and that dorm was handicap accessible but not safe to live in, no first floor rooms):

I've never seen someone in a wheelchair come through recruitment, but I've seen PNMs and members with visible disabilities including my own sister who was born without her left forearm.

I never heard anyone discount someone for membership over a disability and there was never that sort of attitude displayed by the NPC orgs on my campus. That said, I don't know if there weren't PNMs in wheelchairs because they weren't interested or because they didn't feel comfortable, or because they didn't think we'd be interested.
