Need help. Wireless does not work after kernel upgrade

[Andrew Robinson]

I had ndiswrapper and wireless networking working on my eMachines laptop 
running Fedora Core 4 with kernel 2.6.15-1.1831_FC4. This afternoon I 
upgraded to kernel 2.6.17-1.2142_FC4. I upgraded ndiswrapper to 
ndiswrapper-1.18-1.lvn4 and 
kernel-module-ndiswrapper-2.6.17-1.2142_FC4-1.18-1.lvn4.

lspci shows my wireless network adapter:
00:0c.0 Network controller: Broadcom Corporation BCM4306 802.11b/g 
Wireless LAN Controller (rev 03)

I still see the wireless driver with 'ndiswrapper -l':

Installed drivers:
netbc564                driver installed, hardware present

When I try to bring up the wireless interface, I get

[root at proteus log]# ifup eth1
SIOCSIFFLAGS: No such file or directory
Failed to bring up eth1.

In the messages I list below, I see references to "bcm43xx". Was there a 
native driver developed between kernels 2.6.15 and 2.6.17? Should I be 
making use of that? How do I do so? If not, how do I rescue my ndiswrapper?

Thanks!
