Sorry Fujita,  I had to re-install and reboot the system to get those 
details.

The cciss driver is the one that really went haywire for me on the large 
system.

It does two greater than PAGE_SIZE pci_alloc_consistent() calls -- one 
with 0x3a800 and the other with 0x4800.  Both calls seem to complete but 
my cciss was completely hosed.  I couldn't access it at all :(

The tg3 (which alloc's 0x8000 and 0x4000) actually worked but the 
network wasn't working very well.

P.
