OpenBSD 4.5 and XVR500

	Hello,

	I'm trying to install OBSD 4.5 on a Sun Blade 2000 (dual 
UltraSPARC-III+/900, 2 GB, 2 FCAL disks and a XVR500 framebuffer). I 
don't know OpenBSD very well, I only have installed a long time ago this 
system on an IBM laptop, but I know some other unix system (Net, 
FreeBSD...).

	I have burned a CD to install a minimal system. My blade boots on UP 
kernel, but kernel hangs (without panic or other information) just after 
ifb initialization. I have tried SMP kernel. Same result, kernel hangs 
just after ifb initialization and without any information.

	So. To install system, I have modified intput and output devices and I 
have installed it with a serial console. Now, basic installation is done 
and I try to reboot on internal disk. Kernel is booting and hangs just 
after framebuffer initialization. I have tried to modify output device 
to force a resolution (screen:r1280x1024x60) without any result. Rarely, 
kernel boots until login prompt.

	I haven't found any bug report. I don't think I have made a mistake. 
Are there any workarounds ?

	Regards,

	JKB
