You are talking a _lot_ of bullshit, and I'd really like to tell
you to fuck off, because you have no clue how software development works.
But I (as the primary developer of ssb) like to resolve the issue, too.
Please provide more information on the actual _issue_.
In this whole mail you basically only state that:
> IRQ 255 looks very idiotic, doesn't it?
Explain that in detail, please. Why do you think it's wrong?
Which IRQ number do you get with the old b44 driver?
Thanks for your testing. That is why -mm exists.
Next time without bullshitting, please.
