ewwww this makes the driver quite a bit less readable!

for example

-#if LINUX_VERSION_CODE >=3D KERNEL_VERSION(2,6,0)
-       /* This is 2.6 specific, nicer, shorter, but not in 2.4 yet */
-       DEFINE_WAIT(wait);
-       prepare_to_wait(&priv->reset_done, &wait, TASK_UNINTERRUPTIBLE);
-#else
-       DECLARE_WAITQUEUE(wait, current);
-       set_current_state(TASK_UNINTERRUPTIBLE);
-       add_wait_queue(&priv->reset_done, &wait);
-#endif
+       PRISM_DEFWAITQ(priv->reset_done, wait)

why not just make a DEFINE_WAIT() and prepare_to_wait() macro for 2.4
instead ?? so that you can just have the 2.6 version in the code and do
2.4 compat in a clean header, as opposed to fouling up the entire driver
with it.
