Err, yes it does support samplerate control of speed - the left inlet is 
a signal inlet, and I checked the source code to confirm it:

// d_osc.c
static t_int *phasor_perform(t_int *w) {
     t_phasor *x = (t_phasor *)(w[1]);
     t_float *in = (t_float *)(w[2]);   // (1)
     t_float *out = (t_float *)(w[3]);
     // snip weirdness
     while (n--)
         tf.tf_i[HIOFFSET] = normhipart;
         dphase += *in++ * conv;        // (2)
         *out++ = tf.tf_d - UNITBIT32;
         tf.tf_d = dphase;
     // snip boring bits

The line marked (1) gets a signal vector from the dsp graph, and the 
line marked (2) increments the phase by each signal element.
