[PATCH] Add module parameter support to tdfxfb

[Steven Walter <srwalter@yahoo.com>]

The attached patch adds support for module parameters to the tdfxfb
driver.  As it stands, these options can only be changed if the driver
is compiled into the kernel.

This patch is incremental to Paul Mundt's patch.  Its very
straightforward to apply to 2.4.7, but I'll gladly make such a patch if
there is demand.  All comments are welcome.
