All 'psuedoramdom' generators are predictable, that doesn't make
them less 'good', except for cryptographic applications.

It's a perfectly good choice for this application. Its only problem
is when you use it to generate random *bits*. Witm m = 2^N, the
lower n bits will form of cycle of lenght 2^n, so e.g. the LS bit is
just altermating 0,1,0,1,0,1 -- not very random.
