Nope. The hme is the 100Mbps version of the same thing, I'm pretty sure. The 10Mbps one is still just an le device, which is Lance ethernet, for the chip that was used on it. And the on-motherboard 100Mbps ethernet devices were also hmes, and there was no intrinsically attached SCSI adapter there (although there would be one on the motherboard, I don't think they were closely integrated like on the SBus and PCI cards).

Of course, I could be remembering incorrectly, as it's been quite a while since I dealt with 10Mbps ethernet, especially on a Sparc.

Regardless, it's all very standard stuff and you'll have no problem getting it to work under Linux.
