Hi Bruce,

Thanks for the feedback.

This bit is wrong - I need to use the .tar.bz within the .zip.

Ah, ok - to my (untrained) eye the use-case looked completely different based on the example.

I have now (with the above change). However, it looks as if something within the build is referencing the host file system when building.

I'm building for ValleyIsland 32-bit:

  1) If I configure the drivers for 32-bit there is a linker error complaining that elf 32 and elf 64 aren't compatible (host is 64 bit);
  2) Everything appears to build if I target 64-bit, but the installer tries to modify /lib/modules/3.2.0-67/..., which is also part of the host.

Looks like I need a patch ;-) Any pointers to where I should be looking would be appreciated as this isn't my normal area...
