Odd. I have OBP 3.something in my U5. According to the OpenBoot 3.x Quick Reference (search for 802-3240-10 on sunsolve.sun.com), it should have a 'sentenv output-device' option, although it doesn't tell me there if it can be used to change the resolution; perhaps it's only to switch to/from a tty? Anyway, http://www.gentoo.org/doc/en/gentoo-sparc-obpreference.xml more or less implicidly states that output-device can be used to change resolution, since it gives an example for how to do that, and then adds: "Additionally, for users using the onboard video card based on the ATI Mach64 chipset (Ultra 5/10 and Blade 100/150), you will want to append the following to your kernel boot options: [...]" Unfortunately, my U5 is broken, so I can't verify this. I hope you can still access your OBP via serial console; OBP is very useful when something is wrong or something needs to be changed (eg, boot from network instead of hard disk).
