I have had problems with vlb cards running above 33 MHZ.  The effect appears
like the loss of interrupts or extreme interrupt latency.  I have seen this
especially bad on amd 486dx2/80 (vlb clk 40mhz) and 486dx2/100 (vlb clk 50mhz).
I suspect the problem would exist on 486dx50 as well.

The effect seems to be very pronounced on vlb disk controller cards with
other i/o on board.
