Those asics did not have an internal thermal sensor on the chip so if the board has one, it would be an external 3rd party i2c chip, most likely an lm64. The radeon kernel driver will attempt to load the appropriate i2c driver if the vbios power table lists an attached i2c thermal chip. See radeon_atombios_parse_power_table_1_3() in radeon_atombios.c in the radeon kernel driver (drivers/gpu/drm/radeon).
