On another note, I have a MS-9618 mainboard by MSI w/ Intel ICH7R
southbridge and Intel 82573V/L that seems to work well:

- vmstat -i output after bootup
interrupt                          total       rate
irq256: em0                          752          1
irq257: em1                            9          0

- a traversal of a webserver pointing at /usr/share/doc using wget
FINISHED --10:19:51--
Downloaded: 532,781,578 bytes in 25931 files

- same traversal on a non msi kernel from nov 2
FINISHED --10:23:26--
Downloaded: 532,781,578 bytes in 25931 files

so roughly no change there.

versbose boot snippet of the onboard em adapters.
