Does that mean that it's normal for RedBoot to unmask serial
interrupts?

My Ethernet driver initialization routine ends up calling
cyg_drv_isr_lock() and cyg_drv_isr_unlock(). The latter
enables interrupts.
I can add #defines to my driver code to turn those into noops
unless CYGPKG_NET is defined.
This raises the question: is it OK to call those two routines
during network device initialization?
