Mauro,
This patch is missing a few things, so it won't work.
The required - and some desired - changes are in the comments below.

For consistency with the other defines for I2C addresses, please rename
this to "IVTV_ADAPTEC_IR_I2C_ADDR"

Please add this comment to the right of the new entry: /*
IVTV_HW_I2C_IR_RX_ADAPTEC */
You will need to add in ivtv-cards.h:
#define IVTV_HW_I2C_IR_RX_ADAPTEC (1 << 21)
and modify this define in ivtv-cards.h
#define IVTV_HW_IR_RX_ANY (IVTV_HW_I2C_IR_RX_AVER | \
IVTV_HW_I2C_IR_RX_HAUP_EXT | \
IVTV_HW_I2C_IR_RX_HAUP_INT | \
IVTV_HW_Z8F0811_IR_RX_HAUP | \
IVTV_HW_I2C_IR_RX_ADAPTEC)
In ivtv-cards.c, for the "ivtv_card_avc2410" entry, you must modify the
".hw_all" to be:
.hw_all = IVTV_HW_MSP34XX | IVTV_HW_CS53L32A |
IVTV_HW_SAA7115 | IVTV_HW_TUNER |

To avoid walking off the end of "hw_devicenames[]", you will need to add
a new entry to the end of "hw_devicenames[]":
"ir_video", /* IVTV_HW_I2C_IR_RX_ADAPTEC */

You are switching on a value from a different set. Instead use:
case IVTV_HW_I2C_IR_RX_ADAPTEC:

Please add a /*FIXME */ comment here, so that I will remember to figure
out the default keymap and RC protocol type.
