And thus my desire is to just disable BEDBUG as its not something we  
really use and its anywhere near correct for e500.  I'm not even sure  
how it got enabled.  Its also a little weird in that its enabled based  
on having PCI enabled:

#if defined(CONFIG_PCI)
     #define CONFIG_CMD_PCI
     #define CONFIG_CMD_BEDBUG
     #define CONFIG_CMD_NET
     #define CONFIG_CMD_SCSI
     #define CONFIG_CMD_EXT2
#endif
