Class4 / Class 10 SD cards on NetBSD

[Ottavio Caruso <ottavio2006-netbsd%yahoo.com@localhost>]

Hello,

apparently on my Thinkpad X61 the sd card reader is attached to the
PCI interface, not the USB hub

bash-4.3$ dmesg|grep sdh
sdhc0 at pci3 dev 0 function 2: vendor 0x1180 product 0x0822 (rev. 0x21)
sdhc0: interrupting at ioapic0 pin 18
sdhc0: SD Host Specification 1.0, rev.4
sdhc0: using DMA transfer
sdmmc0 at sdhc0 slot 0

I am not sure how this plays with NetBSD. Would it make any difference
in speed if I use a class 10 vs a class 4 SD card?

And I must have read somewhere (maybe a forum) that *BSD cannot boot
from an SD card. Please tell me it's not true. (Well, I know it's
possible on the Raspberry, but on the PC?)

Thanks
