[LAU] wireless and realtime?

Hey all, I've been having problems trying to find a realtime kernel that has decent wireless support. I tried JAD 1.0, which performed quite nicely, but did not have adequate wireless support or even madwifi "out of the box", which I apparently need. I'm running a D-Link DA-2320 PCI card which uses the Atheros chipset (madwifi?) and when I inquired about it on their forums it didn't seem to take much priority. I think 64Studio also struggled with this card but it's about the only chipset locally available that has any track record at all with linux. This card IS quite nicely supported under Ubuntu and family "out of the box" but the kernel supplied with UbuntuStudio, while it handles my wireless nicely, is more sluggish, in regards to latency, than the vanilla Ubuntu kernel. I'm not afraid to try building a kernel for myself, just wondering why so many realtime kernels seem to lack the proper wifi support that IS available to linux in general? I also seem to remember reading somewhere some problem with certain wifi drivers co-existing with a stack or something needed for realtime? Thanks in advance, Jon
