 I found out what was missing.  It turns out that the patch to siside.c
 (v. 1.35 -> 1.36) was valid, but it was also necessary to sync the
 timing settings from FreeBSD 10 (sys/dev/ata/chipsets/ata-sis.c, lines
 266-267).  Here is the patch:

 With this, I was able to mount the CD-ROM and see that it was very
 busy while reading files for the following test:
 
 find /cdrom -type f|xargs wc
 
 I also built and burned an install CD-ROM with the patched kernel.
 The CD-ROM booted and the installation was successful.
