I just opened up my Dell Latatude 6410 and I noticed what looked like a PCI-e slot sticking out from under the displayport cover, so I unscrewed the displayport and lo and behold it was what appeared to be a 3rd Mini-PCI-e port marked with the 'Dell ON' logo. though the space was *maybe* an inch in size so it would have to be a half-card to fit...
Anyone know if this is a fully-functional PCI-e port? Perhaps intended for a SSD to run the Dell ON system? (for those unfamiliar, it's a <2gb dell-made linux system to let you 'instantly' access email, web, and a few other limited features without fully powering up the laptop, it's usually installed on a 2gb partition on the HDD)
