You can only pass a parametrer to a kernel.
Then you can edit the init scripts from the kernel so that it parses
this parametre and does something or another thing.

This is a typical boot entry:

title mylinux
root            (hd0,7)
kernel          /boot/vmlinuz-2.6.20-12-generic
root=UUID=a3965c0c-5c7e-425d-a6e6-850cd0ad90c0 ro quiet splash locale=es_ES
initrd          /boot/initrd.img-2.6.20-12-generic
savedefault
boot


The kernel is: boot/vmlinuz-2.6.20-12-generic
and all the rest of the line:
root=UUID=a3965c0c-5c7e-425d-a6e6-850cd0ad90c0 ro quiet splash locale=es_ES

is what the kernel can read and interpret thanks to init scripts.

Yes, you could add something like:

myconf=/mnt/hda3/myconfig.cfg

Check grub documentation / manual or the many menu.lst that have been
uploaded to the linux forums.

Grub.
