Are you sure? The 82660 seems to support it, as far as I understand the
manual. And what about devices which need PCI mem-space, like a graphics
card?

I also checked the esiop(4) driver and it requires PCI memory at the PCI
mapping register 0x14 as well, or it will fail.

Also the OFW device tree lists memspace ranges. Why should it, when it is
not supported?

IMHO the system will never work without it. :|

Thanks a lot. Got it!

From the SCSI host? No.

But when I'm configuring the ethernet device to I/O space to make it work, I
receive a single IRQ 11.
