Hi,

My first edition toilet seat model works with the following patch:

It would, or you could just use the patch that enables the modem
serial port on the iBook; it works fine, I spent most of the last
Christmas holiday dialed up from NetBSD on my iBook.

(I should probably just commit this. Would whoever posted this patch
speak up so I can give them credit?)

BEO ADDITION

It's PR 15505

The important code is:

+       /* XXX Enable internal modem (KeyLargo) */
+       if (PCI_PRODUCT(pa->pa_id) == PCI_PRODUCT_APPLE_KEYLARGO) {
+         printf("enabling KeyLargo internal modem\n");
+         out32rb(ca.ca_baseaddr + 0x40,
+                 in32rb(ca.ca_baseaddr + 0x40) & ~((u_int32_t)1<<25)); /* powe
r modem on */ 
+       }
