Hi.. I'm still battling with the cd-rom drivers under 
-current.. I really don't understand why this is so difficult.

sbus0 at mainbus0 ioaddr 0xf8000000: clock = 20 MHz
dma0 at sbus0 slot 0 offset 0x400000: rev 1+
esp0 at sbus0 slot 0 offset 0x800000 pri 3: ESP100 20Mhz, target 7
scsibus0 at esp0
esp0 targ 0 lun 0: <FUJITSU, M2694ES-512, 811F> SCSI2 0/direct fixed
sd0 at scsibus0: 1033MB, 1819 cyl, 15 head, 77 sec, 512 bytes/sec
esp0 targ 6 lun 0: <SONY, CD-ROM CDU-8012, 3.1a> SCSI2 5/cdrom removable
cd0 at scsibus0: cd present, 987504 x 512 byte records

bash# mount -o ro /dev/cd0a /cdrom
/dev/cd0a on /cdrom: Operation not supported by device

I used the MAKEDEV in /usr/src/etc/etc.sparc to create the cd device
files.  

bash# ls -l /dev/cd*
brw-r-----  1 root  operator   18,   0 Feb  2 14:17 /dev/cd0a
brw-r-----  1 root  operator   18,   3 Feb  2 14:17 /dev/cd0d

My kernel contains 

dma0    at sbus0 slot ? offset ?
dma*    at sbus0 slot ? offset ?
esp0    at sbus0 slot ? offset ?
esp*    at sbus0 slot ? offset ?

# old sun4c
le0     at sbus? slot ? offset ?
le*     at sbus? slot ? offset ?

bwtwo0  at sbus? slot ? offset ?
bwtwo*  at sbus? slot ? offset ?
cgthree0 at sbus? slot ? offset ?
cgthree* at sbus? slot ? offset ?
cgsix0 at sbus? slot ? offset ?
cgsix* at sbus? slot ? offset ?

scsibus* at esp?

sd*     at scsibus? target ? drive ?
st*     at scsibus? target ? drive ?
cd*     at scsibus? target ? drive ?

I've tried this using both a DEC RRD42 with an SDEV_NOLUNS entry in
scsiconf.h, and a genuine sun drive. (Shown above in dmesg output.)

Why on earth do these both fail?  I've got -current as of 26 Jan, 
including kernel and userland binaries.

-Chris
