OK I've delved into this a bit deeper...
It looks like there was a patch to the envctrl driver way back in 2.2.16
which changed the way the driver found the environment controls on the sbus.
- if (!strcmp(edev->prom_name, "SUNW,envctrl"))
+ if (!strcmp(edev->prom_name, "i2c")) {
My Prom returns the names the old way, like this...
ebus0: [auxio] [power] [SUNW,pll] [sc] [se] [su] [su] [ecpp] [fdthree]
[eeprom] [flashprom] [SUNW,envctrl]
So it seems the driver isn't finding the hardware. Prom version problem
perhaps?

Is there anyone with an E450 for whom envctrl works?

Hi,
I just finished installing Debian Woody on an Ultra E450 without major
problems. The only annoying thing is the systems fans keep running at
full
speed.
Previously this system was running Solaris 2.6 and the fans ran at full
speed during boot. After a successfull boot they switched to 'low'
speed.
How can I silence my E450 :)
I recall that there is a kernel config option (compile time) for a
module to handle this.
I _think_ I included this as a module in the default kernels. Give
modconf a look to see if there's something in the sparc specific modules
(like an env module or something).
