We have a DMA32 zone now, lets use it to make sure the card
can reach the memory we have allocated for the video frame
buffers.

Hi,

did anybody already pick up, comment, review Gerd's patch ?

Walks in into his own home like a stranger ...

Gerd, THANKS for all you did.
It was a incredible lot!

Hermann,

I just picked it today. I was out this week due to a physical damage at
the hd on my notebook, were my mailboxes are retrieved. Only today I
have it on a stable condition to return back to activities, successfully
recovering my /home on it.

Mauro, Gerd,

sorry to be a pain with this one,
just thought it could be a missing each other.

Our maintainers don't need to excuse for anything!

Adrian and all, thanks for fixing the remaining bugs.

Cheers,
Hermann
