Thanks for the suggestion, but it doesn't help. I don't think this is a 
low-memory machine - it has plenty of memory (1G + 512 swap),  and most 
if it is unused. The gnome resource monitor shows 30-40% usage, and it 
doesn't spike at all when steam is used.

I see some libraries didn't prelink in the log, so I'll try Rob's 
suggestion, and see if prelink helps things. I am not optimistic though 
- I've seen this problem for a long time...
