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.
