Following the upgrade of my T42 to the latest and greatest Ubuntu Release, I updated the Ubuntu-on-T42-Howto.
No news regarding the new Ubuntu version, though - everything still works like a charm.
But there was a (not Breezy-specific) issue with OSD display, forcing you to restart acpid once logged into X to make OSD messages work. I tend to reboot only for kernel upgrades, so I didn’t take notice of this problem. Thanks to Edward Mendelson for pointing this out.
For more information, read the updated howto.
