kernel kraziness

[Ralph Pichie]

Early Friday, I did a major update on my main laptop, including some
some very essential packages. Later that day, I found that my wifi
card did not work anymore and that I had to reinstall madwifi.
Fortunately, I had saved the instructions in my Tomboy notes and was
soon good-to-go, or so I thought.

Attempting to reboot again, I found that Ubuntu 8.04 would no longer
start, even in recovery mode, until I rebooted and chose an older
kernel as a boot option. I have since edited my Grub menu so that the
older kernel is the default choice.

While the system is functioning, I'd like to use a more current
kernel. Any ideas what might be wrong and how to fix it?

My computer is an Acer Aspire 5315-2176, dual booted with Winbloze
Vista and Ubuntu 8.04. I use madwifi to handle the proprietary
wireless.

the relevant section of my menu.lst file reads like so
