Please let me clarify...

This is a warm reset, not a power-on reset. And yes, there is a Dallas DS1233 power-on reset chip. That is, the chip is running OK, and software resets the device from an FPGA register. On one instance, there is a free-running 11.059Mhz {5V core} oscillator, and the other, it is a 12.5Mhz {3.3V core} system clock. Both cards have similiar reseting issues.
