I actually make it a habit to never use power-save modes on my T23 when I'm using FreeBSD - I got bit badly once. When I did try it, I lose my backlight, my ethernet (since I was using my Cisco Aironet 350 pccard at the time) and IIRC the system locked up shortly thereafter. > The requirements for hints to get the console to work at boot are > surprising. I have never seen this on my T30. As pointed out in another note, this is my fault - I trashed the default device.hints and made a "minimal" version. In my case, it requires entries for sc0 and fd0. > How recent is your BIOS? The latest release was on March 6, 2003. I > found significant improvement in ACPI after upgrading my firmware! I upgraded to the latest BIOS before sending this report - the dmesg output was the same between my older BIOS (December, IIRC) and the latest BIOS. -- Matt Emmerton
