Trednet TEW-229UB no longer Atmel chipset, now Gericom

It's listed on your devices page as an Atmel
chipset  and that it works with your driver, but
my recent experience with one from tigerdirect
shows it to have an SIS 162 Gericom chipset,
different vendor, device ids and all.

There is a vendor driver available, but it is
partly binary, abandoned, and does not compile
on my kernel 2.6.8 mandrake 10.1.  Gericom's web
page says "Gericom recommends Windows XP" right
up front, so no wonder.

Any suggestions on a good cheap adapter I can
replace it with?

Thanks,
