embedded VNC

I need to throw together an embedded VNC tablet. The hardware consists of
a 486DX4, 24 MB RAM, and a 1 GB HD.

I have PCMCIA (not cardbus) slots and I have to support wireless. I can
buy whatever 802.11b wireless card I need. No USB, so I'm stuck with

Anyone know of a canned distro that I can scarf?

This is a one-off type of thing, so I don't want to reinvent the wheel....
