This is a weird pitch. I had a laptop with that resolution and the pitch
was 1376 to round the x-res out to the cache-line size (64 bytes):

1376 * 4 (BGRR) = 5504 bytes (stride bytes)

2048 is _very_ odd too--much too large. Don't unserstand where this diff.
with NetBSD comes from because both bootloaders use the same API calls, and
display the same field as is.

On NetBSD, can you do this:

1. Set (the only) mode:

boot> gop 0

2. Check that there's a `*' next to the selected mode in a `gop' listing

boot> gop
*0: 1366x768 BGRR ...

3. Boot NetBSD from menu; see if display is still garbled.

boot> menu
