Hello Dirk,

Ok, I have tried this out and I can confirm these problems.

The net stuff has been updated by Holger lately. Unfortunately, it does 
not work with 2.5 any more. As Holger has already pointed out, most of 
the stuff can be fixed by #defines in "dvb_compat.h":

#include <linux/tqueue.h>
#define work_struct tq_struct
#define INIT_WORK INIT_TQUEUE
#define schedule_work schedule_task

But: the global lock "tqueue_lock" has gone, a wild guess is that instead of
	spin_lock_irqrestore(&tqueue_lock, flags);
the same effect can be expressed as:
	spin_lock_irqsave(&priv->tq.timer.lock, flags);

One thing left is the "list handling", but I don't know how to fix that, 
not to mention that I cannot test any of these changes... ;-)

Hm, it has been removed by Holger, too, I don't know why. Perhaps the 
users should use "insmod.sh" instead?

If so, please change my excellent documentation the next time... ;-)
