[PATCH 2.5] lasat updates

Hi Ralf,
This patch fixes up the Lasat code so it works as well as 
before the latest chain of updates (which is not quite).
The patch to the PCI code is necessary because I stupidly
copied the code from the mips-boards code which also has the
same problem (writes of full 32 bit words are ignored). 
The people who made pci-sb1250.c seem to have 
made the same error too...
