been trying for a week now. It has a RAchipset (www.ralinktech.com) and ralink have put driver support under GPL recently.
So far I've tried on my RH 9 laptop with the standard RAlink drivers, but after 1 min serious data transfer the laptop crashes with a kernel panic.
I've also tried the open source cvs drivers (www.bb-zone.com/misc/rt2500). Then the laptop stays working but the speed is crap.
There should also be a way with ndiswrapper, you then can use the windows ndis drivers. I haven't tried that yet, I am seriously considering buying yet another PCMCIA wireless card with decent linux support.
