The problem is that both sg and bsg drivers use SG_IO ioctl. sg_ioctl_trans() does 32/64-bit conversion even against bsg header. It messes up bsg header. bsg driver gets garbage. This patch fixes sg_ioctl_trans to handle only sg header (struct sg_io_hdr).

This problem led to a GPF in strncmp() when X was started on my x86_32 systems. X triggered the behavior with a write of "target PCI:0000:01:00.0" to /dev/vga_arbiter. The patch has been tested against 2.6.32.1 and observed to correct the GPF observed when starting X or manually writing the string "target PCI:0000:01:00.0" to /dev/vga_arbiter.
