I am running it daily on an equally old HP NX6310 (I *think* yours has got Core 
2 Duo CPU, whereas mine is the older Core Duo ; 'isainfo -k' will confirm 
this).

Check if the disk controller is configured to run in SATA mode.

Sounds like some interrupt flood to me. Try disabling bits that do not work on 
OpenSolaris, like the BlueTooth. Never had anything similar on this laptop 
under OpenSolaris yet. On an older PIII box under Nevada snv-117 or thereabouts 
I have the top-left-corner jumping cursor, which is very annoying (but then I 
have the same on a different NetBSD machine under Xorg 1.6.1, so my take is 
this is an upstream problem), so at the end I disabled cde-login and gdm and am 
using it solely as a server.

2GB on mine...

On the machine I am presently on (2GB memory, dual Opteron 246), after 20 days 
uptime (rebooted only because an image-update) I have 45% memory use (Firefox 
3.51 being the greatest hog with about 10 tabs open). ZFS is usually taking 
most of the rest for ARC as far as I can gather. I've got

set zfs:zfs_arc_max=831155200

in my /etc/system to limit it's use a little.
