i'm pretty sure that's true -- "uname -r" tells me:
"2.6.35-rc4-rday", while when i start gdb, i get:
...
Core was generated by `BOOT_IMAGE=/vmlinuz-2.6.35-rc4-rday
i don't know how much more confident i can be that vmlinux matches the
running kernel -- that's the only vmlinux file on the system.

i'm not even sure what you're asking -- i simply installed gdb on
this 64-bit version of ubuntu, what else do i need to worry about?
and remember, i did say that this was the first time i've tried this
on a 64-bit system so it may well be that there's something really
obvious i don't know.
