I also have a Dell Latitude D820, with BIOS vA01. I experienced the frozen GRUB boot timer while running some of the Dapper betas, but once I installed the actual 6.06 release, my GRUB timer started working again. I've also never experienced the BIOS corruption issue that others have. I also run 6.06 on a Dell Latitude X300, with no problems. just FYI.
