I've received a reply from Pete Züge at SIEA:

The total for HW, SW, and Accessories was 420 Mio CHF, so we can deduct 20 Mio CHF for accessories.
I notice the person who compiled this list used current X-rates, and not X-rates from Jan 1st 08. X-rate was 0.8830022075 USD/ 1 CHF which gives a total of $353m for 2007 HW & SW
