You need a better grep. Here are the relevant lines from the 4.0
/usr/sys/sun3/conf/GENERIC:
# 3/60 P4 color frame buffer
device cgfour0 at obmem 7 csr 0xff300000 priority 4 # 3/60
# 3/60 plug-in color frame buffer
device cgfour0 at obmem 7 csr 0xff400000 priority 4 # 3/60
# Support for monochrome memory frame buffers on various machines.
device bwtwo0 at obmem 7 csr 0xff000000 priority 4 # 3/60
# 3/60 P4 color frame buffer overlay plane, or P4 monochrome frame buffer
device bwtwo1 at obmem 7 csr 0xff300000 priority 4 # 3/60
# 3/60 plug-in color frame buffer overlay plane
device bwtwo1 at obmem 7 csr 0xff400000 # 3/60
There are 2 flavors of plug-in cg4 frame buffer:
1. The "3/60 color frame buffer", normally shipped with 3/60s; will *not*
work in 4/110s.
2. The "P4 color frame buffer", normally shipped with 4/110s; will also
work in 3/60s, but is not necessarily supported.
It turned out to be convenient to have separate config file entries for
the two types.
