Yes (6386/25, SVr3.2.2), and did run into the same issues as you.

I did leave the asy driver enabled for /dev/tty00 and used FAS (although 2.06)
for additional devices.

Don't try to force major device numbers.  Let the Installable drivers
make the assignments.

You won't have to know the major device.
The "node" entry associates the device name with fas.  

Gory details of installation files follows.  Hit 'n' key now if not interested.


These are the setups that I used for fas installation.  The "*.sav" files exist
because ID will remove certain files from your working directory at installation
time, particularly Driver.o and perhaps space.c.  I keep a good copy of
everything in the working directory under "*.sav" and generate a fresh on
each make.

First, the makefile:
note that fas.h is copied to /usr/include/sys so that space.c will compile

Makefile:
__________

SHELL=/bin/sh
INCLSYS=/usr/include/sys
CONFNAME=fas
LKCONFDIR=/etc/conf/pack.d/$(CONFNAME)
DRIVER = Driver.o
SPECIAL = System Master Node Init 
CONFSPECIAL = $(LKCONFDIR)/space.c
CFLAGS = -O -I$(INCLSYS)

install:
	@-/etc/conf/bin/idinstall -d fas 2>/dev/null
	@$(MAKE) $(DRIVER)
	@$(MAKE) $(SPECIAL)
	@$(MAKE) $(CONFSPECIAL)
	@/etc/conf/bin/idinstall -a fas
	/etc/conf/bin/idbuild
	/etc/conf/bin/idreboot

remove:
	@-/etc/conf/bin/idinstall -d fas

$(DRIVER):	Driver.o.sav
	@cp Driver.o.sav Driver.o

Driver.o.sav: fas.o
	cp fas.o Driver.o.sav

$(CONFSPECIAL): space.c
	@cp space.c $(CONFSPECIAL)
	
space.c: space.c.sav
	@cp space.c.sav space.c
	
Master:	Master.sav
	@cp Master.sav Master
		
System:	System.sav
	@cp System.sav System
		
Node:	Node.sav
	@cp Node.sav Node
		
Init:	Init.sav
	@cp Init.sav Init

$(INCLSYS)/fas.h:	fas.h 
	cp fas.h $(INCLSYS)/fas.h

clean:
	rm -f fas.o Driver.o Driver.o.sav

clobber:	clean

Next, the SPECIAL entries: Master, System, Node, and Init
I happen to be using 4 devices (after the single asy device left there)

Master.sav
________________

fas	Iocrwi	iHct	fas	0	0	1	4	-1
________________


Make these device addresses match your hardware.  Mine is unusual and
four ports on a card share the same interrupt.  Edit your address and
interrupt fields accordingly.

System.sav
________________

fas	Y	1	7	1	5	1a0	1a7	0	0
fas	Y	1	7	1	30	1a8	1af	0	0
fas	Y	1	7	1	31	1b0	1b7	0	0
fas	Y	1	7	1	32	1b8	1bf	0	0

Node.sav

fas	tty3	c	51
fas	ttyM3	c	211

Of course, I have used different device names than the defaults suggested
by the FAS documentation.  The key, though, is that nowhere do I worry
about the major device number.  The fas driver does end up getting
assigned a different major than the asy driver.  The asy driver is left
in place for one device and FAS does the rest. Good luck.
