 First the screen and then the power supply of the Acer 5051AWXMI I've been using for work died some 9 months after the warranty expired.

-I wanted something not too large but with a screen with plenty of resolution.

Or rather installed Debian Stable (currently Lenny) from a CD I had lying around and then upgraded. I need to build some work stuff targetting i386 with GCC 3.3, so for simplicity this is a i386 install, and not x86_64.

-To my delight both seem to work solidly.+Initially both seemed to work solidly. Then, sadly, it turned out this was an illusion. Suspend does seem to be reliable. Hibernate mostly works. Mixing the two seems to greatly increases the chances of the system wedging. The Dell BIOS DSDT shows the usual selection of warnings from the Intel compiler.
  
 I've installed ''uswsusp'' to give me a little console feedback during suspend and resume. This seems to be OK. I tried adding ''splashy'' for some eye candy, but immediately fell found of kernel memory corruption on resume. I suspect this may be an interaction with the kernel modesetting. The modesetting stays, ''splashy'' goes. I've installed ''uswsusp'' to give me a little console feedback during suspend and resume. This seems to be OK.
