Since writing this, I have found the single key line to the Abe White
patch
that helps me.  I noticed that in the 104 version of atyfb that
RagePro LT stuff similar to the hack was added in, so I thought I'd
focus on
what wasn't added.

If I add an immediate 'return' to aty_set_pll_ct, my
system will boot with BootX parameter "video=atyfb:vmode:19,cmode:16". 
I believe
the atyfb driver is at least somewhat working here, because I can run
Xconfigurator and get an FB_Dev X server up, so long as I pick a display
mode close to
vmode:19,cmode:16.  X doesn't work outside of Xconfigurator, but I hope
that's
a different issue.

The relevent part of dmesg:
