I have installed it on 28 production servers with that patch contributed by William Lee Irwin III including Dell Servers and 2 Compaq servers among other types of hardware with 3ware, MPT SCSI, straight IDE, MylexRaid in the mix.

Marcello has announced a freeze on any new features in 2.4, so unless this is considered a bug fix it may not get in.
