Subject2.2.0-pre1 breaks ppa-driver
The assembler changes in ppa.c in linux-2.2.0-pre1 
break detections of a PS/2 parallel port.
Both gcc 2.7.2.3 and egcs 1.1.1 give the same result.

From dmesg:
--------------------------------------------------------------
ppa: Version 2.01
ppa: Found device at ID 6, Attempting to use EPP 32 bit
ppa: Found device at ID 6, Attempting to use PS/2
ppa: Unable to establish communication, aborting driver load.
scsi : 0 hosts.
scsi : detected total.
--------------------------------------------------------------
Workaround:
(disables assembler routines for i386 in ppa.c)
