The card reader very likely looks like one of these, which is first an
external device and then a built-in reader.  These are USB2.  I see in your dmesg:

ehci0 at pci0 dev 29 function 7: Intel 82801GB/GR USB EHCI Controller (rev. 0x01)
ehci0: interrupting at ioapic0 pin 23 (irq 4)
ehci0: BIOS has given up ownership

ehci0: companion controllers, 2 ports each: uhci0 uhci1 uhci2 uhci3

So make sure you have umass in your kernel.  Run 'usbdevs -v' as root to
see if you see any usb devices that might be card readers.  If all else
fails, the sandisk 12-in-1 is $30 from www.bhphotovideo.com and has
worked well for me under various NetBSD versions.  Your system appears
to have an Intel chipset, so it should be ok.
