i have prepared a patch to whitelist that laptop. it would be awesome
if you could compile flashrom with the following line added to the big
array in board_enable.c around line 2400, the exact line does not
matter as long as it is somewhere inside the table
	{0x1039, 0x6325, 0x1019, 0x0f05,  0x1039, 0x0016,      0,      0, NULL,         NULL, NULL,           P2, "Elitegroup",  "A928",                  0,   OK, p2_whitelist_laptop},

after adding that and recompiling, you should be able to use flashrom
again without the laptop force switch (and i could rest assured that
the patch works).
