rt2500 Make error on FC6

[VTLinux]

I was able to get my Wireless PCI card working under FC6 thanks to this forum.!
I have been keeping up with the kernel updates.
Ever since kernel version 2.6.19-1.2911.6.5.fc6 I have experienced problems with the make utility with rt2500. The error listing (below) references compile problems because of argument passing differences.
I've made no changes to the rt2500 version since.
I can't determine how to fix this and would love some help.

Here is a listing of the errors I get during the most recent make attempt.

First and most importantly: I have no experience with wireless in Fedora. However, I do recognize your compile error.

Short answer: Your kernel is too new for the driver you're trying to build.

Long answer: The 2.6.20 version of the Linux kernel changed the internal workqueue API. See this link if you're interested in details. Your driver is coded to use the old API, so it won't build against the 2.6.20 kernel. You need to find a driver for a newer kernel, or stay running an older kernel to maintain compatibility with your existing driver.

Thank you very much jcliburn! At least I know now the reason for the compile error and can pursue getting the driver coded to support the newer kernel.
