You could check for yourself: run lspci -vvxxx after cold and
warm boot from windoze. As for interpretation of the values one
has to consult the pci spec. But it's also possible that irq
routing is screwed up which won't show up in lspci I think.

saa7146_core.c:saa7146_init_one()
...
        /* we don't do a master reset here anymore, it screws up
           some boards that don't have an i2c-eeprom for configuration

/*
        saa7146_write(dev, MC1, MASK_31);
*/

You could check if that makes a difference.
