I think Manuel B. was trying to attribute it to that problem last month
when he asked whether this machine was hw or sw flush. That problem is
apparently with IP[CX] and 1/1+ (and 2? not sure) that use sw flush,
whereas this model has hw flush. This instance might invalidate that
assumption, though, for all I know.

1.5.x isn't *that* far behind ... I wouldn't say they're useless.
