Good news... There is progress. Bad news... not there yet. The kernel
starts to boot and then it hangs.

The one question I have surrounds the patch to
sys/arm/arm/elf_trampoline. The current version I have matches to
version 194609. Is it possible you meant I needed the extra assembly
code from the prior version (188019) to avoid the hang up?

The diffs I have to date is (from a RELENG_8_2_0_RELEASE baseline):

diff -r src.orig/sys/arm/conf/GUMSTIX src/sys/arm/conf/GUMSTIX
92a93,95
> 
> options               MD_ROOT
> options               MD_ROOT_SIZE=4096
diff -r src.orig/sys/arm/xscale/pxa/uart_bus_pxa.c
src/sys/arm/xscale/pxa/uart_bus_pxa.c

diff -r src.orig/sys/arm/xscale/std.xscale src/sys/arm/xscale/std.xscale
2c2
< options               ARM_CACHE_LOCK_ENABLE
---
> #options              ARM_CACHE_LOCK_ENABLE


The output to date is 
U-Boot 1.2.0 (May 10 2008 - 13:33:03) - 400 MHz - 1604
