The latency to expect in this case should be within
several useconds and not harm your msecond stuff.
Inside our HD-recorder we do 4x48kHzx16Bit AUDIO(ISA)
+ 10MByte/s VIDEO(PCI) to SCSI(PCI). In this case we reprogramm
the PCI-scheduler on the motherboard to cut off long term PCI-burst
transfers. This leads to a slightly smaller total performance but
much lower PCI latency (needed for our too small VIDEO FIFO).
!!avoid this if possible, it has to be adapted to every new chipset!!

> The parameter you have to worry about is called "latency" and roughly
it defines how many cycles a PCI card holds the bus before it releases
it again to another PCI card (or ISA for what that matters).
