Thanks for the info Rick. I downloaded the latest Broadcom tg3 driver
(version 3.58b) and README.TXT says that this driver is already part of
the recent 2.6 kernels:

"The latest driver is in the latest 2.6 Linux kernel. It can also be
downloaded from http://www.broadcom.com as a source package, but is
generally not necessary to do so if you are using the latest 2.6
upstream kernel from http://www.kernel.org or one of the latest
vendor kernels from Red Hat, SuSE, or others."

The info from # modinfo tg3 seems to agree as it says that the version
of the tg3 module in 2.6.17-1.2157_FC5 is 3.59.

Is there perhaps a more recent beta driver you are referring to or are
you still saying it is a good idea to try this driver?

Thanks,
Patrick
