Yes, the driver is quite obsoleted.  It was added long ago with
arch/mips/jmr3927 and not maintained long time, as like as the board
itself.

I know both MontaVista and CELF have new driver for the chip.  If
anybody in MontaVista did not complain I can send CELF's one available
at http://tree.celinuxforum.org/pubwiki/moin.cgi/PatchArchive.  (it
needs some changes for recent kernel, for example pt_regs removal, but
it would be easy).

Sergei?
