I hate to even bring this one up but I'm seeing the same symptoms on a k6/2 400, which isn't an SMP box, and doesn't have acpi enabled. The problem is more or less as described earlier, any intense disk access more or less makes X unbearably unresponsive (mouse updates ever 3 seconds or so, same for keystroke echos on xterms). Back under 4.7-R I can remember downloading files from this box over 100Mbps e-net and saturating the line, with X remaining very usable, now it's more like 5MB/s with a semi-frozen X display, so I'm pretty sure the machine has enough muscle to do what I'm asking of it. Took some patience but I grabbed some output from top -S while I was downloading a file over ftp from the k6/2 400, as seen below. Oh, I guess I should mention that as soon as I kill a file transfer X instantly returns back to its normal, usable self.
