Unfortunately, different distributors have different options for
mkinitrd, so you'll have to do "man mkinitrd" and see what the options
are for manually forcing certain drivers into your initrd-file [assuming
you actually NEED to have aacraid, sd_mod and scsi_mod in your initrd -
you really shouldn't need to specify them manually in normal cases - but
if you know you need those, then it's a good idea to force them in there
just in case...]. 

On SuSE 9.x, you specify the moudles you want with -m, and -f, -v are
both "meaningless". 
On FC4, -f means "force overwrite of initrd file", and -v means "print
verbose information". It also has the --with options. Note also that
mkinitrd is a shell-script, so whilst it may not be immediately obvious
what it does, you can "just read it", rather than binary files that you
have to find the source of. 

I also think you should specify 2.6.16.29-xen, but maybe that's only
when you build from unstable? Check what your version is called in
/lib/modules/  - my machine has /lib/modules/2.6.16.29-xen and various
older ones. You need to specify exactly the right version of linux, even
if your initrd doesn't have that name in it...
