I don't have  that option on my version of Eclipse, which is 2.1.  Maybe I 
should have the newer version.  Under "Software updates" I have only "New 
updates" and "Update manager".

This is a really important feature for me, so if I can't find one it may be a 
deal-breaker.

I'll keep my fingers crossed!

I will, but it's been a tough nut to crack.  When I first got this Soyo 
Dragon motherboard, I installed Mandrake 9.1 on the system and encountered 
the hang problem frequently.  Shortly afterwardI had to back off to Mandrake 
8 due to problems getting Kylix 3 running on the newer distro.   At that same 
time I'd just discovered (and disabled) the ACPI option in the bios, so I 
thought I'd fixed it.  Recently I set up 9.1 in a spare partition so I could 
run Eclipse.  In 9.1, the problem was back.  At some point  (but not 
immediately) while running the screen saver, it flashes the keyboard lights 
and hangs, probably some sort of kernel panic.  But there's nothing in the 
log about that, I just see normal stuff like cron messages.  One thing that 
makes me suspect power management was the following, which I see in the log 
files for Mandrake 8 and 9.1 as well as Red Hat 9 (which also hangs):

Mar  6 04:06:41 vaughn kernel: Uhhuh. NMI received for unknown reason 3d.
Mar  6 04:06:41 vaughn kernel: Dazed and confused, but trying to continue
Mar  6 04:06:41 vaughn kernel: Do you have a strange power saving mode 
enabled?

I suppose that may be totally coincidental.  The other oddity about this 
system is that sometimes when I reboot it, it hangs on the reboot, and I must 
press the reset switch in order for it to come up.
