That's not sufficient to identify your card.  ath5k should print more  
detailed information to the kernel log, which is shown by the dmesg  
command.  If it's AR5006 (MAC revision less than 14.2), the card  
should work with MSI turned off.  Just add "pci=nomsi" to the kernel  
command line in the bootloader.  Alternatively, disable CONFIG_PCI_MSI  
in .config and recompile the kernel.

If it's AR5007, the experimental code is being tested now:

Look for the latest compat-wireless.  Some people report build  
problems due to unrelated code in compat-wireless.  It's a known  
problem, which has nothing to do with the driver itself.

I suggest that you subscribe to ath5k-devel, read the mailing list and  
try dealing with the problems that are reported to the list.  You may  
also want to see how to adapt madwifi tracing infrastructure to the  
new mmiotrace code due to appear in Linux 2.6.27.
