I have a 164LX and (barring the time the > heatsink fell off) it has been working very well. Say that after putting a Myrinet or gigabit ethernet card in it ;-) 164LX's share at least some of the problems of early revision miatas. Chris sees slow host->PCI dma bandwidth (~70MB/sec) with his Myrinet card. Whether it shares other, nastier problems (page boundary DMA bugs), I don't know.
