Well, after a hint from Alan I have realized the the problem is "extended
translation" OFF by default in pre13 and ON in pre14&up. It is nicely shown
by the following diff (of /proc/scsi/aic7xxx/0):

In the BIOS setup I have:
"Host Adapter BIOS" : Enabled
"Extended BIOS Translation for DOS Drives > 1 Gbyte" : Disabled
and it was working this way in the old Adapted driver.
Unfortunately I will not be able to diagnose the floppy problem before
Friday.
