You probably are wrong because the CS 233 are not the only cards involved in
overclocking but are the only that seem to be affected by the LR bug:
I own a "BPPC" sold as a 603e+ at 160Mhz and in fact if the processor is
actually rated at 160 Mhz by motorola, PPCtool on the P-UP side return
175Mhz and PPC Info gives me 176.6 for Warp up.
In fact I have a 50 Mhz crystal and P5 has set the PLL divisor at 3.5X, so
they have overclocked my card at 175 without niticing it to me.
But AFAIK, my card doesn't suffer from the LR bug (but how can I detect it)
and I don't see the reason why a hardware pb (overheating or whatever you
want) can affect W-OS and not P-UP.
