This problem was fixed by upgrading the bootstrap software from 11.2 to --

BOOTLDR: 7200 Software (C7200-BOOT-M), Version 12.0(24)S

Then the bootldr could read the disk1 entry and load the IOS from it.

So the router loaded 12.4(13b) fine now and is running with that. 
Unfortunately, this did not fix the problem it was hoped it would fix, the 
problem with QoS over multilink PPP.
