As per my post a while back, I'm still chipping away at trying to get the bochs_drm framebuffer fired up in QEMU's sun4u. So far I've managed to figure out that I need to add Simba support to QEMU which is taking longer than expected as various OSs make assumptions about the interrupt-swizzling for Ultra 5 on-board devices. However outside of the interrupt issues, I now have something that seemingly boots a kernel built from source and initialises the IOMMU correctly. Now all I need to do now is figure out why the DRM memory mapping routines never map the framebuffer to a virtual address and always fallback to returning the physical address... ATB, Mark.
