This is handled by the GDAL EHdr driver.

Looking at the code :
* skipbytes: yes, taken into account
* bandrowbytes: only taken into account if nbits < 8
* totalrowbytes : only taken into account if nbits < 8

Not sure why the last 2 fields are only taken into account conditionnaly.

If that doesn't work for you, as suggested by Kyle, you could use 
VRTRawRasterBand specification.
