Actually, I wasn't aware that was the default.  None of my apps
use RedBoot services, and I don't remember ever having to
change anything, but I may have just picked the right defaults
when I created the HAL for my target platform.

Browsing through the ecos.ecc file, here are few likely
settings:

turn off CYGSEM_HAL_VIRTUAL_VECTOR_INHERIT_CONSOLE
turn on  CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_COMMS
turn on  CYGSEM_HAL_VIRTUAL_VECTOR_INIT_WHOLE_TABLE 
turn on  CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_DEFAULT
