I've written such a program. The basic idea is to load data that looks like
a cartridge into bank 0, $8000, and reset to 64 mode. The 64 mode Kernal
POLL sees the "cartridge" and runs the code within, which sets the disk
drive to 1541 mode (ignored with an error if the drive already is a 1541),
and then LOADs and RUNs the dependent program.
Alternatively, the original poster might convert the program to run natively
on the 128. After all, you have the bonuses of 2MHz mode and 80 columns.
