Fix up LANCE ethernet DMA mapping under Solaris 8 on SPARC32.
It seems that Solaris doesn't set up a DMA mapping for the LANCE DMA buffers
and hence must inherit this from OpenBIOS. To make things more complicated,
Solaris appears to assume that the buffers are fixed at 0xff000000 rather
than detecting this information from the OpenBIOS IOMMU pagetable before
switching. Mimicking this behaviour with a fixed location allows Solaris
8 to correctly use the network card under QEMU.
