LinuxQuestions.org - Insmod "unresolved symbol" errors

Okay, I realize that this is a problem with a driver that probably no one has ever heard of, but I'm not getting much help on their forum. I'm trying to install the open-source driver for the ACX100-chipset network card (my D-Link DWL-520+). It is one of those "$ make" supposedly simple installations that does access kernel includes. Anyway, I do that and then run the install script, which is mainly just an '$ insmod acx100_pci.o firmware_dir=firmware debug=0x9b' command. The problem is that I get the following load of unresolved symbols:

Can anybody recognize these symbols as being part of a certain kernel option, or software package? Any guesses or recommendations of another possible problem are very welcome.

As far as I know, I have all the necessary kernel options (CONFIG_NET_RADIO, CONFIG_NET_WIRELESS) installed, as well as the required Wireless Tools package installed. I cleaned up all the leftovers from other kernel installations and recompiled the kernel that I did have. /lib/modules/`uname -r`/build points to the right spot (that being /usr/src/linux). I've tried installing with gcc 2.9 as well as gcc 3.3 installed and with four different versions of the open-source driver. The driver is technically in alpha stages, but there have been so many success stories that I'm convinced it can work, and no one else has posted any similar problem to this on their forum (acx100.sf.net).

Finally, those of you who know about the TI ACX100 chipset, I was able to install and insmod Ivor's acx100sta module just fine, and get associated and connected to the internet. However, it consistently locked up the card after transmitting a few kilobytes (15KB or so) and the only way to fix it was to reinstall the driver ... again and again. I've checked other forum threads and the people that have had this problem haven't seemed to have found a way around it. However, if anyone reading this does know a way to fix that, I'll be happy. I would prefer to get the open-source driver going, since it's got a lot more options, etc., but any internet connection will do.
