OK, thanks for the report.
Summarizing for others: to force the media type with the 2.4 kernel you
either need the updated mii-diag, or to make the following change to tulip.c

Line 3058
-	case SIOCGMIIPHY:	/* Get the address of the PHY in use. */
+	case 0x8947: case 0x89F0:
+	/* SIOCGMIIPHY: Get the address of the PHY in use. */

Line 3066
-	case SIOCGMIIREG:		/* Read the specified MII register. */
+	case 0x8948: case 0x89F1:
+	/* SIOCGMIIREG: Read the specified MII register. */

Line 3099
-	case SIOCSMIIREG:		/* Write the specified MII register */
+	case 0x8949: case 0x89F2:
+	/* SIOCSMIIREG: Write the specified MII register */

That's a more difficult problem.  I can't get the information from
Conexant to configure the chip to correctly report the Tx status.
