Default Sun XVR-600 in 24-bit mode

Hello all,

I recently acquired a Sun Blade 1500 workstation. This is an Open Firmware-based SPARC machine so it's a bit different than the x86 hardware I'm used to. Solaris 10 doesn't run well at all on this machine, and OpenBSD appears to be the only other OS with support for the XVR-600 graphics card it's got.

So far I've got Xorg configured with the wildcatfb driver, which works fine on its own. The only issue is that wildcatfb will only cooperate with the framebuffer bit depth it's running on when X is started. The XVR-600 starts in 8-bit mode by default. In Solaris the fbconfig utility is provided to get it running in 24-bit mode, but I can't find a similar utility in OpenBSD (4.7/sparc64) to achieve this.

It's possible to set the framebuffer resolution and refresh rate from within the Open Firmware prompt, but to the best of my knowledge no way to set the bit depth.

If anybody can point me in the right direction to get X running in 24-bit color on this card, I'd very much appreciate it.
