Both kernels would boot the 10.2.3 disk, but neither kernel would boot 
the 10.2.4 disk.

I had a hunch that the kext cache might be a problem. Reading through 
bootx-mol main.c I discovered the option, and tried:

kernel: /home/jclark/MacHome/6.4/mach_kernel
mkext-1: /home/jclark/MacHome/6.4/Extensions.mkext

...where Extensions.mkext is the cache that was pre-generated by the 
10.2.4 installer (copied to linux). 10.2.4 boots OK with this configuration.

It would appear that 10.2.4 installer may have done something odd to the 
HFS+ partition that confuses bootx. I ran a block compare of the first 8 
partitions (between 10.2.3 and 10.2.4 disks) and they were identical. 
 The boot sectors (0 and 1) of partition 9 (HFS) were zeroed on the 
10.2.4 disk - not that that should matter.

FYI:  had trouble building bootx-mol. I had a quick scan of the 
mol-devel archives but could not spot anything related.
