Hi Grant, ...

I am unsure if this is a regression with regard to Sylvain's patch, or
somethign else, but it is no more possible to build bestcomm modular :

.config snipplet leading to this : 

CONFIG_PPC_BESTCOMM=m
CONFIG_PPC_BESTCOMM_ATA=m
CONFIG_PPC_BESTCOMM_FEC=m
CONFIG_PPC_BESTCOMM_GEN_BD=m
CONFIG_FEC_MPC52xx=m
CONFIG_FEC_MPC52xx_MDIO=m

This is building against the 2.6.23 tree, with assorted debian patches
applied, and the latest version of this and domen's patches.
