,I was running Lucid 5.2.8.6 on a Dell optiplex 780, Intel Core 2 Duo CPU E7500 @ 2.93GHz, 4g RAM, w/ATI RV620 LE Radeon HD 3450.
There being no compatible ati driver
Just ignore me if I am off the point, but I have a HD 3850 that works with the ATI driver in Quickpet with Lucid 5.2.8 all versions (2.6.33.2 kernel). Ibiblio is horrible, and to make it worse some of the ibiblio mirrors seem screwed up to me--they serve bad copies. You might try using the built-in radeon driver and just adding Xorg-High (which is glx and a faster download). That is the open source solution. The open source drivers do not depend on the kernel version so it may work with whatever lupu you are using. In general they might not be quite as fast but they should provide acceleration (hardware-based direct rendering). Personally I use the open-source drivers.
Yes, that is the appropriate open source driver, Xorg-High provides hardware acceleration (hardware-based direct rendering)Also when I do the search for a video driver I am told to install Xorg_High which I have done. However, I am not sure if I have the best driver. I have attached the output from open glx.

On your shutdown problem, did you try Lupu 5.2.8.005 or LupuPlus 5.2.8.005? It might matter, or it might not. Lupu 5.2.8.6 is a more direct descendant of LupuPlus 5.2.8.005.
