The following appears as the instruction for Box 2 of the 2008 5498:
Box 2. Rollover Contributions
Enter any rollover contributions to any IRA received by you
during 2008. Include a direct rollover from a qualified plan
(including a governmental section 457(b) plan) or section
403(b) plan. Also include any qualified rollover contribution, as
defined in section 408A(e), from an eligible retirement plan
(other than an IRA) to a Roth IRA. For the rollover of property,
enter the FMV of the property on the date you receive it. This
value may be different from the value of the property on the
date it was distributed to the participant.
It appears that direct Rollovers to a Roth IRA from 401(a), 403(a) & (b) as well as 457(b) plans are reported in the Rollover Box of the Roth 5498 and the Roth IRA box is checked in Box 7 instead of reporting these transactions as conversions in box 3.
Is this a correct interpretation?
