In pre5 the sg driver tries to set up both address
and page+offset in scatterlist entries. Unfortunately
asm-i386/pci.h's pci_map_sg() contains this check:
if (sg[i].address && sg[i].page)
BUG();
which kills that strategy with the sym53c8xx driver.
The sooner we get rid of address in struct scatterlist
the better ... the address,page+offset duality is a mess.
Strange that Andi Kleen had problems compiling ide-scsi,
it compiled and worked on my UP and SMP machines (AMD and
dual Celeron respectively).
Sg patch (which has been already sent to Jens) follows.
