ok, that's looking better as i now have the following:
$ mkimage -l /var/lib/tftpboot/cuImage.tqm8xx
Image Name: Linux-2.6.37
Created: Fri Dec 2 18:53:22 2011
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 1325774 Bytes = 1294.70 kB = 1.26 MB
Load Address: 00400000
Entry Point: 00400518
$
which suggests it's safe to TFTP it to 200000 given its size and the
load address, so ...
=> tftp 200000 cuImage.tqm8xx
TFTP from server 192.168.202.100; our IP address is 192.168.202.79
Filename 'cuImage.tqm8xx'.
Load address: 0x200000
Loading:
... snip ...
done
Bytes transferred = 1325838 (143b0e hex)
=> imi 200000
## Checking Image at 00200000 ...
Image Name: Linux-2.6.37

Entry Point: 00400518
Verifying Checksum ... OK
=> setenv bootargs console=ttyCPM0,115000
=> bootm 200000
at which point i get the kernel uncompressing, followed by several
lines of garbage, suggesting that perhaps my minicom setup is not
right. any final suggestions about console port setup? i get the
feeling i'm really close ...
