Thank you.

The first reference shows:

Product: 	Fedora
Component(s): 	kernel (Show other bugs)
Version(s): 	14
Platform: 	x86_64 Linux

I could not find a similar item in the second reference.

If I correctly understand the first reference, the issue is restricted 
to X86-64, and thus must be an issue either with the way the 64 bit 
kernel handles the 64 bit instruction set architecture extensions to the 
32 bit architecture, the 64 bit compiler, or a specification error in 
the driver when used in 64 bit mode (e.g., a long unsigned int that must 
be 32 bits but is mapped to a 64 bit value in error in the device driver 
source code or the linkage between the driver and the rest of the kernel).

Does anyone know the correct syntax and file entry to make the kernel 
automatically load the driver during boot?

Thanks,

Yasha Karant
