IMO, humans will tend to mix up which module arguments belong to which module.
See my proposal below.

May I suggest a small change to the syntax:

Specify the arguments for the module with "load" rather after the --

Above example would be then:

menu=Boot Xen:modules enabled;load /netbsd-DOM0 bootdev=wd0a ro 
console=pc;multiboot xen.gz dom0_mem=65536 console=vga

This form of syntax will a) scale with more modules and b) the configuration
is easier to read & handle for both parser and the human.
