Basically the answer was RTFM. The way to tell if the card is 24 bits is
to ensure it has 4M mappable memory.
Under Solaris 2.6 a patch must be installed (105362-17 according to
Caper Dik) to replace the m64config utility for one
that has an option for -depth. You can run m64config -help to get all
the optiosn available. The manual page on my 2.6
system is incomplete. (On 2.7 it seems to be fine.) (** I installed
105362-16 until I can get 105362-17 **)
Todd Herr told me the patch is on the Sun Ultra 5/10 Software
Supplement CD in the ShowMeHow CD package that shipped
with the system. Also look at page 1-15 in the Sun Ultra 5/10 Software
We used 'm64config -depth 24 -res 1152x900x76'
A note from Davin Milun stated :

Once the m64 is set to 24 bits you have to setup the Xserver properly.
The following is a suggestion from
Russ Poffenberger :

/dev/fb0 defdepth 24 -nobanner
Steve Williams provided an OWconfig entry. It also has the refresh rate
bumped up from 66 to 76. Our users like this too.
Casper Dik also pointed me to the FAQ #3.56
Thank you all for the clarification:
