I have got the same problem. 6730b downgraded to XP and no drivers for Intel(R) ICH9M LPC Interface Controller - 2919. Do you have also problem with brightness control (Fn- f9, f8) while XP is loaded ?

I have solved the problem (I am the same guy as above) I can't reproduce exactly how I handled the situation, because it was my MILs laptop, and I brought it already back to her.
You have to go to hardware configuration and double click on the yellow exclamation. Then you have to click the button for installing the driver. After a while there will be asked for a cd-rom of a company named Infineon with the driver. If it is oke, you can see the name of the driver required in the field. This driver you can find on the driver cd-rom which was supplied with the laptop. Search for it with the search option in explorer. I believed it was in a folder named misc2 or something.
If you can find the driver, I have to go to my MIL and see on her laptop for the right driver

Do you know what LPC 2919 is intended for?
Is it necessary?
Is ifxtpm.inf the correct driver info for this device?
I just downgraded a DELL XPS 1640 to WinXP Pro and it shows same issue.
Vista boot shows the driver as msisadrv.sys (sytem32) for this device. I wonder if I can use the same file for XP?
