Will G4/733 daughtercard work in a Cube?

[PowerMac]

I plan to buy a processor upgrade for my G4/733 Digital Audio 
("original" g4 tower, not quicksilver) and was wondering if my cube 
would be able to use the "left over" G4/733 processor card?  I realize 
the Digital Audio Mac has a 133mhz bus, and my cube has a 100mhz bus so 
the card would run slower in the cube (or possible faster?).

Any thoughts on this?  Has anyone tried this or something similar using 
a processor card from another Digital Audio mac (466, 533)?

Thanks,
Jason
