Dell Mobile Broadband 5620 driver #

Transplanted a Dell Wireless 5620 EVDO-HSPA Mobile Broadband Mini-Card from a two year old Latitude E4310 to a new Latitude 6430U. Attempting to install the official driver returned "Unable to validate model".
Dell ProSupport claimed that the 5620 was not compatible with the 6430U. But that sounded absurd: both laptops had dedicated mini PCIe slots and ran Windows 7 x64. Why should the card not work?
Installed the Dell Mobile Broadband Utility for DW5630 from the 6430U's Windows 7 64-bit page. The client software worked just fine, but the 5620 was still not recognized.
On the Dell forums, darthgeorge mentioned a 1.6GB CAB file that might contain a compatible driver. While that behemoth was downloading, a new ray of hope emerged: the Qualcomm Gobi 2000 Package for Dell shared by blingers: http://dl.dropbox.com/u/72473707/3068cc2.zip. Sure enough, the driver installed easily and the 5620 was recognized immediately by the Dell Mobile Broadband Utility. (Local archive for posterity)
