Sorry for the late reply -- I wanted to attempt to recreate the issue.
Unfortunately(?) I am not seeing any such problem. My card is a PCCard
apparently sold by CompUSA, but the chipset reported in dmesg matches
yours (i.e. RTL8185vD + rtl8225).

I have tried vanilla 2.6.34 and 2.6.35 as well as the Fedora-provided
2.6.35.6-48.fc14 -- all seem to work equally well, despite the annoying
warning that continues to pop-up during scans. (I need to get that
fixed in Fedora!)

Could you try using netconsole to capture a backtrace over an ethernet
connection?

If that doesn't work, you might try doing a git bisect from the last
working kernel (2.6.33?) to the first broken one (2.6.34?).

Thanks,

John
