I did a bit more testing this weekend, I booted the laptop and I got
this in my dmesg: 

ipw2100: Intel(R) PRO/Wireless 2100 Network Driver, 0.44
ipw2100: Copyright(c) 2003-2004 Intel Corporation
divert: allocating divert_blk for eth1
Detected ipw2100 PCI devoce at 0000:02:04.0, dev: eth1, mem
0xE0210000-0xE0210FFF -> 2a701000, irq: 5
eth1: Using hotplug firmware load.
eth1: Firmware 'ipw2100-1.1.fw' not available or load failed.
eth1: ipw2100_get_firmware failed: -2
eth1: Failed to power on the adapter.
eth1: Failed to start the firmware.
divert: freeing divert_blk for eth1
ipw2100: probe of 0000:02:04.0 failed with error -5

Then I can do an rmmod ipw2100 and then modprobe ipw2100 and it loads
fine and I get this in my dmesg:

ipw2100: Intel(R) PRO/Wireless 2100 Network Driver, 0.44
ipw2100: Copyright(c) 2003-2004 Intel Corporation
divert: allocating divert_blk for eth1
Detected ipw2100 PCI devoce at 0000:02:04.0, dev: eth1, mem
0xE0210000-0xE0210FFF -> 2a701000, irq: 5
eth1: Using hotplug firmware load.
ipw2100: attempt to use fw ordinals before they have been loaded.
ipw2100: Associated with 'WLAN' at 11Mbps, channel 11

Then I did an rmmod ipw2100 and then I try to bring up the eth1
interface using the Fedora Core 2 ifup script and I get the first error
message. The only way I can get it to work is loading the module with
"modprobe ipw2100" or else it won't find the firmware. How is the driver
loaded when it autoloads itself through /etc/modprobe.conf? What's
different about this way and doing a modprobe ipw2100 manually?

This is only a minor problem though, the real problem is data
corruption, when I load webpages sometime they don't load correctly,
like html tags cut in half and stuff like that, also images often get
corrupted. Am I the only one with this problem?
