Indeed. :-)
I downloaded mipsisa32 binaries
(http://www.mirror.ac.uk/sites/sources.redhat.com/pub/ecos/gnutools/cygwin/e
coscentric-gnutools-mipsisa32-elf-1.4-2.cygwin.tar.bz2) and now
Redboot -mpg32 seems to work too.
I have a dumb question: what should MIPS ISA 32 stand for? I am acquainted
with the ISA 1/2/3 - but don't get what should ISA 32 exactly represent.

In addition, tried to build the following GCC 3.2.1 targets, but without
success:
mips64vr4100el-elf (target not supported by gcc)
mips64vr4100-elf (odd problem with newlib)
mips64vr4300-elf (odd problem with newlib. sounds the same as above)

I guess that we missed something - so we'll keep on trying.
In the meantime, we are able to use mipsisa32-elf. :-)

Thanks,
Jura
