I noticed an issue with it only passing pings of <= exactly 19028 bytes total size, but it refused to pass just about any TCP data unless you applied persistence (clicking refresh when accessing a web server across the bridge yielded a returned page after about 30 seconds of continuous hits). The good news is, i was able to fix it, the bad news is i dont know how. I decided to cleanly reinstall RH 7.2 and start with todays snap from the CVS tree for hostap. In getting the box set up i noticed the pcmcia config was trying to load a wvlan driver for the card, a bug perhaps, it was the intersil 2.5 mfrid that it found a match on and proceeded to load wvlan_cs. After stopping that and installing the hostap driver, it started working beautifully. If anyone wants more info on my setups feel free to ask.
