Yes.

Actually, "uc0" probably means that the kernel sources are from the uClinux
project.  Board specific patches are unlikely to have any effect on MadWifi
modules, so you can compile it against plain 2.6.9-uc0.

You also need to set the configuration so that the modules are marked ARMv4. 
Looking at a current kernel, it seems that you need CONFIG_CPU_32v4T or
CONFIG_CPU_32v4 defined in .config, then arch/arm/Makefile defines
__LINUX_ARM_ARCH__ to 4, and this goes to the module magic in
include/asm-arm/module.h

Then chances are you'll get MadWifi to work.
