(Thanks to hrw for help identifying this commit.)

In OE version 93d42c42fbac9beca66c0c236f2fb48801155c94 I load my image and am
greeted with 

U-Boot> bootm 21000000
bootm 21000000
## Booting image at 21000000 ...
   Image Name:   Angstrom/2.6.21/kb9202
   Image Type:   ARM Linux Kernel Image (gzip compressed)
   Data Size:    1293875 Bytes =  1.2 MB
   Load Address: 20008000
   Entry Point:  20008000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK

Starting kernel ...

Nice ;)


But in the next OE version (efc0ab0488966ec8b240c345445e8a5fa688b30f) I get the
following:

U-Boot> bootm 21000000
bootm 21000000
## Booting image at 21000000 ...
   Image Name:   Angstrom/2.6.21/kb9202
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    1308944 Bytes =  1.2 MB
   Load Address: 20008000
   Entry Point:  20008000
   Verifying Checksum ... OK
OK

Starting kernel ...

Uncompressing Linux................

invalid compressed format (err=1)

 -- System halted

Not so nice :(
