kernel-2.6.14-1.1831_FC4 breaks wireless

[Peter Smith]

Hello,

I have FC4 running on a Dell X1 notebook.

On updating to kernel-2.6.14-1.1831_FC4, system-config-network "Cannot 
activate device eth1", reporting "tg3 device eth1 does not seem to be 
present".

Rebooting to kernel-2.6.14-1.1656_FC4, eth1 is found as "Intel 
Corporation PRO/Wireless 2200BG", and it can be activated successfully.

Earlier kernels were OK, but -1.1833 has the same problem.

I did not install any kernels between -1.1656 and -1.1831.

Is there any work-around for this?

Thanks in advance,
Peter Smith
