Thank you, I appreciate that.

Of course, my preference would be to fix up the kernel driver.  I don't mind
doing some manual bisection with compat-wireless releases unless you think =
that
would be a total waste of time.  Do you have any sense for what the last wo=
rking
kernel version would have been?

As you suggest, we may need to use the vendor driver in the meantime.  Than=
ks
again for sending it over (although I suspect it is the same version I
downloaded from Realtek's web site).

Thanks,
Forest
