 From glancing at the include file 
(usr/src/uts/sys/scsi/conf/autoconf.h, should be in the exported 
opensolaris), the bits 0x58 enable:

- Global disconnect/reconnect
- Global Linked Commands
- Global Parity Support

Notably it does *not* include global synchronous transfer capability, 
tagged command support or any of the fast/wide possibilities. I can't 
find where the default scsi_options are for the esp driver, but 
presumably it had some of those capabilities enabled, which aren't 
supported by the qemu scsi driver.
