@Colin I had experienced this bug with the Beta. So, before installing
the RC (in the meantime I had to RMA my hard drive) I was able to take a
clean copy of my MBR. Attached is a tarball with three versions of the
first 63 sectors of my disk:

sda.0.beforeubuntu.clean:
 - This is taken with the livecd before installing (but after partitioning with gparted) Ubuntu 10.10 RC
 - The sector starting at offset 0x1400 contains some Dell-specific strings. I redacted my service tag number from here in two places (hence the ".clean" suffix).
sda.1.afterubuntu:
 - This is taken after first successful boot of Ubuntu
sda.2.afterwindows:
 - Finally, this is taken after booting into windows and then booting back into Ubuntu.

I did notice that the situation has improved for me between the beta and
RC. I did not have to recover grub after starting windows, nor uninstall
Dell DataSafe Local Backup. This is essentially fixed from my
perspective, but if you wanted additional improvement, avoiding
overwriting the bytes at 0x1400 would probably be nice. I don't know
what those are used for.
