------- Comment #31 from susemuse27 at gmx.de  2007-08-08 13:27 -------
I adjusted config.opts in terms of io-ports and those are clean now, no 
more "excluding...":
........................................
pcmcia: registering new device pcmcia0.0
cs: IO port probe 0x100-0x2f7: clean.
cs: IO port probe 0x300-0x3af: clean.
cs: IO port probe 0x3e0-0x3ff: clean.
cs: IO port probe 0x4d8-0x4ff: clean.
cs: IO port probe 0x820-0x8ff: clean.
cs: IO port probe 0xc00-0xcf7: clean.
ds: re-scanning socket 0
ds: update device information for 0.0
ds: re-scanning socket 0
ds: update device information for 0.0
ds: registering driver serial_cs
ds: trying to match 0.0 to serial_cs
ds: trying to match 0.0 to serial_cs
ds: trying to match 0.0 to serial_cs...
........................................

that job was easy...
but memory probe still returns the usual
..................................................
cs: memory probe 0xfba00000-0xfeafffff: excluding 0xfbd10000-0xfc01ffff 
0xfc330000-0xfd27ffff 0xfdec0000-0xfe1cffff 0xfe7f0000-0xfeafffff
..................................................

changing the memorysettings in config.opts accordingly doesn't have any 
influence...
thanks a lot so far for your efforts!
