That might be worth raising a bugzilla on mkinitrd for.

I'd suggest something along the lines of:

If the --builtin option is used for a module, skip this test:

if [ ! -d /lib/modules/$kernel ]; then
     error 'No modules available for kernel "'${kernel}'".'
     exit 1
fi

Reasoning: we might be building an initrd for a monolithic kernel with 
no modules.

You'll probably need to expand on this to address the modules.dep issue.
