2.1 kernel headers

[Dana Holland]

I'm trying to upgrade the drivers for a QLA2340 HBA on my AS 2.1 box. 
The README for the drivers say that I need a kernel and kernel-headers 
of at least 2.4.9-e.43.  I was able to use up2date to upgrade my kernel 
to 2.4.9-e.59; but, while I see references to kernel-headers for this 
version, I can't seem to find the kernel-headers download anywhere, 
other than a website called "PoundHost".  Does anyone know the 
background on this?
