Well these versions are pretty outdated. But your problem has nothing
to do with xenomai.
It could be that your kernel config does not enable the driver, or the
card is not even supported by that old kernel.

lspci -v should tell you whether any driver claimed the card, probably

Check whether the kernel supports that card and is configured correctly.
i.e. look for the pci device and vendor id in the kernel code.
You might be missing some ucode-/firmware- packages.
