how to mount memory card identified with ugen0

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

When I insert a memory card, I see:

ugen0 at uhub4 port 5
ugen0: ENE Flash UB6250, rev 2.00/1.00, addr 3

But no umass in the dmesg output nor sd associated with it.

Any ideas?

This is i386 netbsd-MONOLITHIC from May 23.

(On a different hardware, also running NetBSD, I can mount it easy using 
sd -- which uses umass.)
