Ubuntu Lucid Lynx on Toshiba nb 200 slow/no boot

I just upgraded to Ubuntu Lucid Lynx and just found that with the provided kernel the boot is incredibly long (more than 5 minutes). After a bit of upgrading to the last-last kernel available to date (2.6.22-32) with no aid, I decided to have a look around and see what other people were experiencing.

Multiple ubuntu kernels

I am wondering, normal users with Ubuntu and no particular knowledge of the system are doomed having an hundred long kernel list in Grub and the disk filled or there’s an idiot proof way to get rid of oldest kernel?
