Yes. You may use either sprintf that is exported by your kernel or
sprintf from the library. See man ksyms (display exported kernel
symbols). Kernel's sprintf is less rich e.g. it does not support
floating point format (%f) because double-s are not needed in the
kernel.

Not too sure. May be impossible without good understanding of
glibc-2.1.2 functions, not easy. Anyway my ported sprintf works even
for %f.
I agreed with Phil Wilshire to put the ported glibc-2.1.2 on
www.realtimelinux.org after making it a bit more tidy in a couple of
days.
