Do you have to use 2 cells for address? Cannot it be:
 			ranges = <0 0x04000000 0x20000
 				  1 0x05000000 0x20000
 				  2 0x06000000 0x20000
 				  3 0x07000000 0x20000>;

 I tried this first, but it didn't work, and ranges translation
gave me something really weird (like addr = 0x80 and
size = 0x04000004).

Did you change the address-cells to <1>?

 Of course i did.

 I don't quote the rest because i simply agree to what you've said. Will respin with these changes.
