	Classic problems-after-init.  The driver puts the card into MMIO
mode, but as you can see below it fails to register itself as a display
and then does not return from MMIO mode (known bug) when cleaning itself
up.  I don't know German, but the error looks like a resource conflict. 
The most common causes of this in the past have been that either something
else has grabbed the VGA IO ports (cat /proc/ioports to check) or you have
a COM4 port, which conflicts with the S3 accelerator IO ports.  Also I
noticed that you are using the VGA clockchip driver.  Try using the S3
idac clockchip driver instead - I doubt the VGA one will work in MMIO
mode.
