rescue distro on 128 meg usb key?

["Matt Price" <moptop99@gmail.com>]

hi,

my dad is bringing me an old toshiba tablet (don't have the model
number) that seems to be having serious trouble, possibly a disk
failure.  I will probably install a linux distro on it eventually, but
will have to figure out what makes the most sense for this kind of
machine (limited speed & memory, but pretty specialized needs, esp for
the touch screen).  For now though I just want to try and boot the
thing.  apparently the external usb hard drive my dad has for the
thing won't boot, and I don't have any on hand.  I currently have only
one usb key, which is 128 megs, and I was wondering if anyone knew of
a distro that would run off of a removable medium this small.

thanks as always for the help!
