Ouch. All the USB master chipsets I've seen are PCI based.

That's easy enough. PCMCIA is pretty much ISA bus with a
different connector: 20 address lines, 16 data lines, rd*, wr*,
bhe*, and so on. I don't know the details of a Mega128, but if
you've got an external bus with enough address and data lines
all you need is a bit of glue logic for the bus control lines.
