[pilcher@home ~]$ ldd /usr/bin/gkrellm

        libsensors.so.3 => /usr/lib/libsensors.so.3 (0x4f3db000)
	...

Am I misinterpreting this?

Looks like it must have been patched.

At first, I thought that the "2.0V", "2.5V", etc., were coming from my
sensors.conf:

chip "via686a-*"

    # These are the labels that the VP6 BIOS uses

    label "2.0V" "Vcore"            # in0
    label "2.5V" "Vtt"              # in1 - always around 1.6V, despite
the name
    label "3.3V" "3.3V"             # in2
    label "5.0V" "5V"               # in3
    label "12V" "12V"               # in4

However, I've tried replacing them with:

    label in0	"Vcore"    	    # in0
    label in1	"Vtt"   	    # in1 - always around 1.6V, despite the name
    label in2	"3.3V"     	    # in2
    label in3	"5V"     	    # in3
    label in4	"12V"	    	    # in4

gkrellm -d 0x80 still gives the same message (and still no voltage
sensors), but running sensors on the command line now gives the
incorrect built-in names.

Google found the patch that's been applied to add libsensors support to
2.2.9.  Here is the portion that's causing the error:

+        if (!strncmp(feature->name, "temp", 4))
+          type = SENSOR_TEMPERATURE;
+        else if (!strncmp(feature->name, "fan", 3))
+          type = SENSOR_FAN;
+        else if (!strncmp(feature->name, "in", 2))
+          type = SENSOR_VOLTAGE;
+        else {
+          if (_GK.debug_level & DEBUG_SENSORS)
+            printf("libsensors error determining type for: %s\n", id_name);
+          continue;
+        }

Basically the code is assuming that all voltage sensors will be named
"inX".  The problem is that libsensors has a built-in mapping for the
via686a chip, so the sensor names actually come back as "2.0V", etc.
