Driver used is w2k/xp 32 bit.  WinXP 64 bit driver results in hard lock
requiring hardware reset.

service network restart responds with "wlan0 not present delaying...."

ifcfg-wlan0 is identical to known good config for smp kernels.  Have
tried several versions of ndiswrapper including 1.15 with same result.

Have tried 2054 and 2096 64 bit kernels with same result.

FWIW, CentOS 4.3 64 bit kernels give same result.  Yet, it works without
a hitch on 32 bit kernels and 32 bit smp kernels.

Would appreciate any suggestions.  Have Googled for hours without
finding anything productive.  Thanks in advance.

Bad news.  Your choices are:

1) Run a 32-bit version of FC and hope the Windoze 32 bit driver works.
2) Figure out how to make the 64 bit Windoze driver work with FC 64 bit.
3) Try to find a native Linux driver that works with your existing wireless NIC. 4) Looks like its a mini-PCI card so you could try a different NIC by swapping cards.

I'm running FC4 64bit on an HP laptop and did a bunch of digging last summer when I was attempting to make that combination work. The Windoze driver must match the word size of the Linux kernel for ndiswrapper to work (both 32 bit or both 64 bit). Could be things have changed since then but I doubt it. You might want to look around for a different version of the Windoze driver (e.g., if this is a laptop, from the laptop manufacturer) or, conversely, a plain vanilla driver from the card manufacturer and see if it makes any difference.
